Loving the wit in the upgrades! All round great game. It feels balanced and progression is at a good pace.
I managed to somehow go into the negatives when buying upgrades (see screenshot below), but other than that, no problems!
Great work!
Thank you for providing feedback, this is something that i have also noticed but a bit too late and no clue on how to fix just yet, but thanks for pointing this out.
I'm glad you enjoyed the game :)
