Wow, the artistic style is such an appeal! I was curious to see what other drawings that you came up with - I was looking forward to even more after the game.
Although the gameplay is relatively simple, I think what engaged me is definitely the different levels and drawings.
There was one level I struggled on for a little bit, and it was the one with the head shooting the balls. The heads appear without any warning, so I died multiple times just from the heads appearing. One suggestion is to add some sort of warning to give a player a chance in those situations.
Overall, amazing work in just a week! If you have the time, please give our game a try and let us know what you think!
