Rridgway : I don't really understand about what glitch you're talking about, but I dislike glitching, so I won't try this. Apologies.
Yrr : I try every move everywhere, so every time I don't use the sliding, it's because it's slower to do so. Actually, I realized I might have lost some frames doing a 2nd slide since the lag after cancelling the slide got Wario slower than if he would have just run. Sometimes I can't explain why sometimes sliding looks wayyy faster than walking, but isn't.
Thank you very much for the hint and the compliment, I might get back on the run now.
EDIT : Oh and what do you mean by running and walking?
EDIT 2 :
Here is about lots of things I have written about speed and all that, you can also see the input display of my WIP.
Actually, I think I got wrong about the sliding, but it may be useful once I have the garlic powerup, since your slide gets faster then.
