Thanks for giving it a try.
The ESC is requested and on my to do list.
The battles are really not where they're supposed to be at at the moment, it's hard to show off without content or show upgrade systems without that content in.
I might see about a glow setting to turn it down, but it will eventually be a "neon horror" type of feel, that's the goal anyway.
The boss is a bit broken at the moment.
These are all on the todo list for a future build, probably DD71 I think.
