I loved this game! It's really fun, if feels very balanced and fair, and I love the way the upgrade system works! One of the only Wowie Jam games I've actually replayed after winning, and I could definitely see a future for this if it was more polished and expanded upon.
Also, in a way, it's kinda similar to the game we made! It feels like we had a similar initial idea but went on different directions. Would love if you checked it out!
