Steam review snapshots
Enter a room, use your twin-stick shooting to clear said room of baddies, repeat until you’ve downed all the bosses then go…The result of all these decisions is a roguelike that is both breezy and immediate above all else; once I became accustomed…Coop – both local and remote What I think could be better: 1.The wide selection of character equipment allows for great replayability and the coop sets it apart from similar titles and is super…Why it fits
Check it if you want action, adventure filtered by roguelike, co-op, local co-op.
