Thanks for letting me know it runs with WINE, I appreciate it.
You are 100% correct about the enemy damage bug. They also don't display the correct directions when the map is rotated. I admit the enemy ai was kind of rushed (in addition to fixing the already mentioned bugs, I would've liked to have implemented some real path finding) as I was kind of more focused on getting the levels to generate and display nicely. Actually, there was a bunch of stuff I wanted to implement that never made it in - like instead of just having a simple damage up upgrade, I wanted to have a shop/inventory mechanic where you could buy stuff like stronger arms/different weapons, faster legs (maybe swap in wheels/tank treads), maybe like limited use stealth items and stuff - but I digress.
Whoops, I edited the game description with the correct debug controls, thanks for the heads up on that too.
