You definitely should be proud of this game! I have spent more time on this game than any other game during the jam — and that hopefully tells you something.
I just like how everything comes together in this game. It is simple, and it is clean. It is balanced quite nicely but upgrades still feel powerful and different from each other. The game has just enough polish to make it feel tactile and good to play.
I definitely recommend you to keep working on this after the jam!
