Been playing for the last week or so.
Very fun! I'll defintly grab a copy when it's on Steam!
I would love to see an Endless Mode! I could even see things like skill trees and loadouts (pure rng is fine too), more maps, could even do a story mode; survive 10 minutes one map, move on to the next with harder enemies.
Anyways, very cool for demo, I look forward to buying the finished version.
