I couldn't run this on linux for some reason (it said the pck was missing even though it was there, weird), but it worked fine on wine (windows emulator on linux).
Loved the menu! credits, and customizable input mappings!
The music gave it a nice atmosphere. I liked the attack sounds, and the map design!
One criticism I can give you is that you could navigate menus using the arrow keys, but not wasd, and having to change from using wasd to arrows just to manage the menu was a bit annoying. This is really just a minor detail though.
Nice game!
