Took me a bit to get used to the controls (which I appreciate being simple), but once I did the game was really fun to play. The artstyle was also great for a game with a lot happening on the screen.
I kept needing to adapt to each round, so the gameplay never got stale. The builds you can make feel almost endless. I got to wave 9 before dying. I was pleasantly surprised to see I got to keep some weapons I unlocked.
This genuinely might be one of my favourite jam games ever. Great job for something made in a week.
