Thanks for playing! I didn't want the chasms to work like barriers because I wanted you to be able to run enemies into them if you want. But I will at least add feedback to make it clear you're losing health when that happens. I have a few changes planned that will fix the problem you had with the rat tunnels. I'm going to change the role of stamina so that it won't force you to depossess enemies, make it impossible to depossess while inside rat tunnels (or over chasms with a bat), and make rats and bats respawn where they're the only way to reach somewhere.
