Reviewing.
So I don't know much about this game, so I wanted to see why certain obvious shortcuts weren't taken, like in level 3 where you could stay on the roof and fall down. Turns out I didn't realize this game had fall damage, so it's better to take a more intended route otherwise you will be sent back earlier in the level.
So I noticed some of the IGT for some later levels were slower than the published TAS, and after trying to improve them myself to match the published TAS, I can understand why nobody likes TASing this game. Not only is lag annoying, but this game has some of the most flimsy physics ever. For example on the ramp down in Stage 2, it's faster to get off of it a bit later as you can keep some of your speed. Though you still have to wait for the bridge to drop down, while at the same time deal with lag everywhere from the enemies. when I tried to enter the pipe, I either enter it too late or too early, and making it so I have to add frames just to adjust for this.
However, I did manage to save 13 frames on Stage 2 (didn't match IGT of publication), but this causes way more lag in stage 5, completely ruining everything. I couldnt even get that same glitch jump once this starts happening. I will put this up for anyone who want's to use it:

Overall, this is a well made TAS despite the frustrations it causes. I don't know how you manage to do it adelikat.
