Yes there was another game crashing bug introduced with latest hotfix. I rushed to fix it and the patch is now up. Please redownload anyone that has downloaded the game during the last 15 minutes! Hopefully everything works now? Thank you for quick report!
Haha I'm glad you enjoy it.
And for the anime noise, SPOILER, whenever a runner gets hit by a rock it selects a random scream sound and there's a very very tiny chance that the burly dwarf screams "itai!" like a little anime girl, as a dumb silly joke lol. In the full game you would've gotten a steam achievement! xD
