Can you make speedruns made in reskins of the game? Like Super Mario Flash Land? Or nah?

what are you asking ? i dont understand

If you speedrun a reskinned version of the game, like super mario flash land or super mario bros flash, does it count as a super mario flash speedrun? Those "games" are just reskinned versions of super mario flash. There's no difference gameplay wise (i think). I just thought that would be kind of cool.

no play super mario flash

Yeah most of them are just reskins, but they might tweak some things while at it and we're not gonna check each one or try to draw a line as to what's valid and not. It's easier to just say play SMF.

iirc there's a Sonic reskin, and it's the best of all of them, but, sadly, not allowed. :(
