The game is pertty nice but it has a lot of little problems.
The physics of the jump doesn't fell very good wihc is unfortunate considering it's something you do the whole game.
The game is also veeeeery slow wich is not very good , especially when you have to restart the whole level when you die. Kind of a shame because the grappling hook was a really nice mechanic so if the physics were totally on point the game coule be really fun.
The graphics are very simple but still very effective.
Overall a fun little game that suffer from it's phisics, hope this can help you improve the game :)
