I have much to say to this game, because i see potential in it, but it has some issues.
1. The game is too complicated too fast. By that i mean: Don't throw everything at the player at once, but rather introduce everything step-by-step. E.g. in the first level you could already have 1 grappling hook and you could have a little text that says: Look, here you can see how many times you can use the grappling hook. In level 2 you could introduce fruits, and in level 3 you could introduce breaking walls. Just introduce everything slowly.
2. I know: The wall being destroyed is the main mechanic of your game, but it's actually the thing i found the least fun. It's just frustrating and when it happens i think: "Oh, well, then let's restart". I would rather have wall climbing or the grappling hook as your main mechanic.
3. I noticed that the door is over the player rather than the other way around. Just a minor bug.
Other than that, this is a fun game and i hope my critique didn't sound too harsh, i just wanted to say some things that could improve it. I hope that my feedback was maybe even useful, and it would be really nice if you could check out my submission too. Thanks! :)
