Steam review snapshots
Because underneath its pretty accessible and intuitive surface, is a ridiculously robust action game with a dash of mystery dungeon roguelike flavoring…But I think that also means I'm overlooking some rough spots that you might be so forgiving of, like the inventory management…It’s easy to see how a lot of these combinations can spiral into crazy synergies and builds, especially once you start factoring…Very fun simple action game where you explore a tower in mystery dungeon style!Why it fits
Check it if you want action filtered by single-player.
