The speedrun.com page looks great. This should be a great place to record runs and stuff. I just have a few suggestions.

Rules: Timing starts on first frame of fade in and ends at the end of the player animation while picking up infinity jump. As long as you follow this timing method, retimed runs should line up perfectly with ingame times. Of course, retiming runs isn't a big issue right now, but it can be in the future. Other than that, I don't know if we need any other rules. This game is pretty simple.

Categories: Any%, Any% Glitchless, 100%, 100% Glitchless. 100% runs would require all 8 powerups with infinity jump last because the category is more fun when you aren't able to fly everywere lol. I would suggest using "Any% and Any% Glitchless" instead of "Glitches and Glitchless" because this is standard speedrunning terminology. For glitchless runs, I don't think the distinction between FJ and NFJ is necissary. After thinking about it, I realized that being able to jump on signs and flags shouldn't be allowed in glitchless since preforming difficult skips using signs and flags goes against the spirit of glitchless. Plus, according to the current glitchless FJ rules, jumping off of the flag to skip the double jump powerup at the start is allowed which doesn't seem like an intentional choice. I guess if you wanted to keep FJ and NFJ, you would have to write detailed rulings for whether you can do regular flag jumps, flag super jumps, or flag glitch jumps. This seems unnecessarily complicated, so I would actually just prefer banning all 3 from glitchless.
