sometime from roughly 2016 to 2019 (I think it was 2017-2018 but I'm not certain), there was a platformer I used to play during lunchtimes at my school. it was a cute, level based platformer where you controlled a creature, guiding it through levels. you could also pick up powerups or defeat enemies (I can't remember which) to change the creature's abilities. I remember there was a grass powerup and a fire powerup (but I know there were more,) and there was a level where you had to parkour up to a higher level (visible from the ground), where you would have to jump onto blocks of ice, which were slippery and would fall down if you spent too long standing on them. I remember getting stuck on this level and not being able to go further, which is one of the reasons I stopped playing. the other reason I stopped playing is because my school blocked that game (Don't know why, it was very non graphic.) the school later banned cool math games altogether, and years later, I have forgotten most of the details, including the name. I really hope it can be found, it's one of my fondest memories. I truly hope it hasn't been lost.
below I will list suggestions it is NOT, when I start getting them.
Do you remember or have a general guess on what artstyle the game had? Was it pixel art, 3d, detailed shading, or flat 2d art? Maybe if we have a general idea of what art style it had, we could narrow down what game it could've been.
