The game plays, sounds and looks great! It's really fun and has real potential as a pure scoring game, the only thing I could mention is that I didn't realize the potion was actually killing an enemy each time until actually looking at the score so that could maybe use some more clarity, and I'm worried someone might simply try and play it safe and very, very slow and just throw a special on single enemies as soon as they spawn and get a huge High Score?
I really enjoyed this and it is now one of my favorites in the Jam, amazing work!
