I think this is a great and polished game. I played up to level 6.
Small feedback: there was some confusion with what the bucket did, as it seemed to fill to 5000 and then go back down. Also, when I pressed escape to attempt to pause it, I was not able to get the game to continue.
I liked the feeling of the game, seems like most of the mechanics and themes are fairly well integrated. It plays very smoothly, and was quite fun :).
