Thank you for feedback! Yes, we didn't make cooldown after movement and that kind of hurts. And splash damage is a bug - character is way too fat, apparently.
You dying on back track is on me... there is a healing room between that boss and trap room, but looks like its kind of out of sight and that is a huge flaw in level design. And yes, it was a spinner turning you around in there.
And yes, we really need to get those volume sliders next time, so people can tune what and how loud they want to hear.
And again - thank you for playing!
