Great little game! This needs to go on mobile!
There are little tweaks and things that could make it better but overall I really like it. In some areas it seems that its impossible to go through without losing a life.
I really like how with breaking stuff you can lengthen your rope and you can go a long way without upgrading your rope too much if you are good at the game.
I think it definitely needs to be easier in the beginning though to hook players. If they get stuck on the second gold gem they won't play for long.
Also I think the players hitbox should probably be a little smaller.
Overall great game, I like it! If you decide to continue developing it where can I follow the progress?
