Fun game, love the humour and the art style! Couple of notes:
- It would be great if the coins stayed where they are after I fail a level, sometimes I only want to move one coin but I have to replace all of them!
- The player moves a little slow for my taste!
- It can be hard to tell what the radius is for the player to see the coins, I think a circular outline would be good to aid in placing
Other than that, really nice game!
