Very fun platformer! The animations and the sprites are excelent and I really like the light effect as if the character was glowing. I think that could look really cool on a cave or underground level. I like the detail that the longer you press the jump button, the higher you jump, not a lot of platformers have that. But I think you should be able to do most of the jumps with the lowest jump and reserve the high jump only for a few. When you try to do a very short jump and you dont reach without holding the key it can feel a little unresponsive. Really fun game overall I could have played a lot more levels without getting bored!
