I like it a lot but it's frustrating that pressing escape closes the game immediately. Twice now, I instinctively pressed Esc instead of R to restart and had to redo the game from the beginning because of that :/
Also, I couldn't figure out what that red goo does once it's broken.
Other than that, I think it's a great game. Victory screens are fun, sound effects are fun, and the game design of the characters interactions is definitely interesting!
