Nice game.

My only compliment is that you jump with space while moving with the arrows, if you'd move with AD it wouldn't be that weird, but it's a bit weird for me like this, maybe because I need to use two hands for a simple three direction movement.

Cool game, feels like a mix of jump n' run and riddle game and is challenging. 

The sliding mechanic feels weird for this type of game. E.g., at the beginning of level 2, if you are not in the center of the block but slightly on the left, you will slide into the fruit.

As a minor nitpick, I prefer the music to continue playing instead of restarting each time you die or click something in the menu.

The theme implementation is very nice. I will just note you about the life system at the top left (it doesn't make a lot of sense once you die more than 3 times).

This is a really cool concept, this gave me Cat Mario and troll game vibes. There are two spikes on the second level that aren’t working, even if I landed on them I still died, so I couldn’t progress farther than level 2.
