I've done some in depth analysis of how your character's speed works in this game, because I intend to improve the current run! :) Here are my results:
I've done a graph that explains how the game calculates your speed when on the skateboard:
Perhaps a little confusing, but let me explain: When on ground, every time you advance 1 frame while holding down B+right, the game checks your current speed. If it is less than 80, your speed will increase by 3. So your top speed is 82, you will get this speed by holding down B+right when standing on ground with speed 79.
Getting speed 79 isn't trivial, you have to make a jump to get it - when in air, you accelerate/slow down by 1 per frame, so by slowing down to speed 79 right before I hit ground, I'm able to accelerate to speed 82 immediately once I hit the ground.
There is no such trick when walking, your top walking speed is 75, which I keep until I get the skateboard.
I have made a WIP of the first level. I gained 55 frames on the level (by moving slightly faster), but lost 4 frames after the level due to having more life left.
Here is the WIP.
And I read something about warps in this game in
this post, but I don't know any and no FAQ on GameFAQs tells anything about it either (or perhaps I just missed it). So does anyone here know anything of "warps" in this game?
Oh, and with school and all, I don't know when this will be finished, so be patient. :)
EDIT: Allright, so I found the "warp" on level 1, the one where you stand between two totems and a cloud takes you up to a bonus level, which dumps you down to section 4 of the level after you're done with the bonus room. Taking the bonus room is about 3 seconds slower than skipping it.
