i've already made concepts for 2 "areas", like an area named "branch jungle" where, as the name says, you walk on branches and you're in a jungle and wait am i just making a legally-not-wood-zone-but-looks-like-wood-zone thing?

...uhhhhhh i've also made a concept for another area named "antarctic snow" where you walk on giant ice cubes with enemies like a walking icicle with glasses, penguin robots and clouds that try to kill tux by sending lightning bolts at him even though that'd be better for level where you walk on clouds

the art style would either be pixel art or like the old supertux art style. also wondering whether i could just turn this into a supertux fangame but there's already a sonic?-like supertux fangame called supertux advance (it's more like a mario-but-you-go-fast sort of game which is actually pretty fun)

the player would be able to do a move similar to a spin dash but it would just be sliding (you'd charge up the sliding and then slide)

there would be a health system instead of mario-like power ups or sonic's rings
