So, you can technically beat Mouse, but I accidentally cranked her health WAY too high before shipping (i was testing with an upgrade that gave you double damage and didn't properly account for it T-T) so that along with poor balancing in general leads to a really bad boss fight
I want to develop the game further after the jam, and I think weapon upgrades would be sick as beans in all honesty! Thank you for playing, and I'm glad you liked it!
