Great game. Can't wait to see 0.13 and 0.14
I found a game breaking bug regarding the Doomed Frenzy skill.
When I used it on the Sump City boss it swung about 60 times until he was defeated. When I used it recently in sump city on a normal enemy from a compromised position (he was the only one left) it swung until he was at 0 endurance and then just kept swinging forever, never letting the game progress.
Also, I have a huge list of ideas for this game if you are interested, that build on what is already present :)
