i have cleared all the levels
it was slightly agonizing. please do check on the hitboxes but more importantly the origin of the character. when you turn left or right it shifts their whole body a significant amount and usually shoves them into one of the spike-like things (this is especially visible in the water stage)
you can't control the height of the jump, and you move way too slowly for what you've gotta cover
it's difficult, but it's not because the stages are well-made. there aren't even any moving elements in any of the current ones
music is neat tho
