I liked this game. The visuals are excellent, the theme is handled well, and the overall experience is quite addictive. The main thing I felt was missing is a stronger sense of challenge: enemy spawns, several minion types, or something along those lines would add a lot. The minions also feel a bit too slow, heavy, and sluggish to control. It feels like this could become a very compelling and addictive game if developed further, especially with more work on the gameplay loop.
