I found it frustrating that the space bar was the shoot button, and it made me bind it to my mouse instead 😅. I really enjoyed the upgrade system with its many great options. It feels like you have the bare bones of something great here, and I can tell the game wants to be something more, but it seems like you just didn't have enough time. For what it is, I really enjoyed playing it, and I would love to see this continued in a future round.
