Nice concept! I liked the idea of reinforcing and trapping my dungeon to ward off those pesky adventurers. Things did get a bit chaotic to my taste once more enemy waves spawned, but that's mostly because I'm bad at these defense style games.
Thanks for the comment! I agree about the chaotic nature of the game. I was playing with the idea of having the whole map visible including enemies so it's easier to plan out traps. I suppose that could be a different game mode.
