General notes
In all parts there are small mistakes here and there.
Such as; when jumping from certain heights you won't have to stop for landing if you attack while falling; forgetting what direction to go so you see me go the wrong direction for a moment sometimes; I don't like the jumping - it tends to go unlike you expected causing to miss your jumps sometimes; I don't like the camera - it follows too slow, it's just bad overall; I go by the convos slowly so people can read them, don't know if its included in the game's total time, but I don't think it's a very big deal anyway; ladders - you can jump up on them + you can pull yourself up at the very end, although that doesn't always work which then will cost several seconds. and due to the camera it can happen that while you're jumping a ladder you miss and fall back down to start going up over again; killing some enemies where it's not necessairy; getting hit where I could have avoided it; you can use the flute (once you got it) to go to places you've been before - which can save alot of time in travelling, but I don't know if using the flute (you'll be flown to the place by a dragon) is included in the game's time, but I could still have probably used it to my advantage in a few places more than I did; switching a character where I shouldn't have; using magical powers - must stand still or it denies; not picking up several 5-Ryo coins to save several seconds later on; accidently switching items/weapons instead of using the item I had in the first place.

Part 1
Didn't need to get the Map of Japan.
Missing a jump thus fell in the water, embarrassing 13 seconds.
Flying carpets - I've had the key after destroying only 2 of them once instead of 5, costs a few seconds, nothing much.
Maybe it would have been faster if I got that fortune doll behind the "blocking hand" right after I beat The King Robot Congo instead of getting it later on.

Part 2
I should have picked up the fortune doll on Musashi later on, 20 seconds.
Wartime Kabuki Robot Kashiwagi - I didn't remember Impact could do the "Lasermouth", so I didn't use it, overall, I've beat him about 2:30 (2,5 minutes) faster on later tries.

Part 3
Fish Catching - lost some on the 3rd blue fish, 2nd yellow fish, 5th & 8th red fish.
In the shrine - I fall down all the way to the ground level after getting the top fortune doll, but perhaps you can fall closer to the other fortune doll in there saving possibly 10 seconds.

Part 4
Got hit and fell in the water on my way to the 1st fortune doll, 7 seconds.
The Gold Fortune Doll is quite difficult to get, you need to walk over a thin rope for it. 25 seconds.
First room with ghosts - I accidently picked up Mr. Arrow.
In one of the rooms with ghosts I took a picture but I didn't need to do so.
I did the room with the last key pretty badly.

Part 5
I could have done the first fortune doll later on to save a few seconds.
I forgot about one of both fortune doll in Aki - Nagato, so I got it later on, would probably have been faster if I had gotten it first time getting there, since I also get the other fortune doll then.
I went back in a door I didn't need to go in, costing a few seconds.
The stairs to get back out.. when I climb it with Goemon, it wouldn't let me jump up thus I fell several times, very annoying and quite embarrassing.
I could have gotten the Surprise Pack later on, with Sasuke's jumping power, it would have been faster, probably about 30 seconds.
In the part where you go to the top using the fishes, I missed on of the first jumps and fell in the water, 20 seconds.
Thanks to the camera I had to wait another go before jumping on one of the fishes, 8 seconds.
The Ghost Robot Tsurami - In his 3rd fase, I missed hitting the red plates once, about 30 seconds.

Part 6
I think I took a bit of a longer path to go to the gym for Goemon's magic power and on the way back aswell.
I could have gotten 120 Ryo first time I get into the Castle, probably would have saved some time.
Missed a jump twice.

Part 7
On my way to Mokubei for the 2nd time, I use the dragon to go to Oedo Town, to realise later on that I could have gone to Kai's Coffee Shop instead, saving almost a full minute. Shame on me, shame!
Another embarassing mistake: I miss a jump when climbing the mountain on my way to Mokubei. 20 seconds.
In the room with the floating platforms I wanted to jump on one but it just didn't perform the jump, so I fall in the water and get back up to fall in the water again not much later. 20 seconds of suffering.
The Charming Mermaid Thaisamba 2 - overall, I've beat him about 1:30 (1,5 minutes) faster on later tries.

Part 8
The fortune doll on Kii - Awaji Island, it took me some time to find out where to jump again.
Found out that the flute doesn't work when you're swimming, so I decided to kill some enemies for Ryo.
Might have saved upto 45 seconds if I just had picked up enough Ryo earlier.
Very embarrassing - after getting the last Miracle Item, I went the wrong way, to make it worse - I accidently started talking to someone whom's convo I couldn't cancel. Then for some reason I lied down.
About 20-30 seconds lost, depending on if convos take up off your game time.
Another very annoying time costing one - The very next fortune doll that I get with Sasuke's jump power, going back down, the camera stays looking from above, so the ground from above is in sight and I can't see where I'm going, costing me a good 30 seconds.
Last fortune doll before going to outer space - I went back in the water and changed to a mermaid but I didn't have to, 11 seconds.

Part 9
In the room with the first Gold Key I could surely have gone faster using Sasuke's flying power.
On the way back I could probably have jumped somewhere to get to the door faster.
In the room that you open with the first Gold Key, I fell off once, several seconds.
same room, flying went wrong once, about 6 seconds.
annoying rose-throwing dudes, not that easy to avoid and if hit it's pretty nasty... I got hit 4 times by these.

The Final 2 Bosses:
The Great Peach Mountain Battleship Balberra - I've always found this one annoying, so I surely could have saved time here, since I never beat this one too well.
The Fairy of Love and Dreams D'Etoile - I've beaten this one at least 40 seconds faster on later tries.

I could go into deep detail about all of the fights, but I shall not due to it being some time since I ran it and I have forgotten if I wrote any comments back then. A perfect run of this could possibly be less than 10 minutes including cutscenes, but I am not that perfect. Missing with the chain pipe can cost some seconds.

• Wartime Kabuki Robot: Kashiwagi (1:41)

  At the time of recording, this fight had become completely natural to me. Since this fight goes along a specific pattern most of the times it will not be difficult to pull off, as long as the boss does not do something unexpected.

• The Charming Mermaid: Thaisamba 2 (1:56)

  This fight also follows a pattern most of the times. I miss a kick before her going underwater, but that doesn't cost any time since then I would have been unable to kick her right before her going underwater anyway. I miss the chain pipe twice at the end, too.

• The Great Peach Mountain Battleship: Balberra (2:04)

  This fight goes almost flawless. Getting the Laser Mouth to connect is quite difficult and missing it means a restart of the run, basically. There is probably time to shave off by exactly calculating how much ammo that must be collected from destroying shots, too. Do notice that I have a margin of one shot when firing the final Laser Mouth. Two less hits and I would have failed to destroy it.

• The Fairy of Love and Dreams: D'Etoile (1:47)

  This fight is the worst of them, but I still did better than Wouter and I got under my target time, so... I start with a spectacular chain pipe miss, but this boss likes moving around and using his shield so a couple of misses is to be expected, more-or-less. Some shots that appear to be misses are also blocked without him using shield due to the temporary invincibility these bosses have when performing certain moves. I also fail at using the Super Punch at one point, but I do not think I lost any time due to it. He does try and start one of his super meteor attack, but I intercept that with a Laser Mouth. And a short while later he delivers himself to me for the final blow.

  I did fairly good I think. When adding the time fought it ends at about 7:28. I have 160 Oil and 58 Ryo when the fight ends. And as I said there is time for improvement if anyone feels like it. I did this run mostly to test my DVD Recorder, anyway. It should work for longer runs, hopefully.
