Wow, really really impressive. I managed to clear it on my fourth try with a score of 7844880. Really really great level design and patterns. I feel like the popcorn forced me to stream a little too much, but then I realised I could just avoid summoning reinforcements so often... so definitely a nice risk/reward mechanic there. I also liked the blade forcing you to point blank enemies, and it seems like you deliberately made it relatively safe to do so. I actually have no criticism to give, sorry... This could totally be spun into a larger game.
