I will definitely be adding map variety if I make another game like this, I didn't have time to figure out how I'd do it in this one but it's on my list of things for the sequel
I'd love to add traps that activate once per round, so you can goad enemies into them, or pits that you could shove enemies down for instant kills. And also improving the ai to allow for multiple player controlled characters, and possibly walls that block line of sight, ect...
Glad you still enjoyed it regardless :)
