The game has solid mechanics and fun upgrades. Most of the upgrades are cool and scale in fun ways, though I would recommend avoiding the bouncing bullets in most cases. Simple gameplay loop, but fun and challenging. Multiplayer is through steam invites, and the game is more fun with another player to be back to back with. I have enjoyed my time spent in the game (which is more than what is logged on steam since I helped playtest a bit). Would definitely recommend if you want a fun, simple, roguelite to do with a friend or two.
