Steam review snapshots
About 2 hrs of playtime, anything after is idling for cards.Some good boss fights would have really made this game a lot better but unfortunately there is only a couple of different…The hand-drawn sprites are backed up by truly powerful dialog, with a multitude of branching paths allowing for infinite replayability.Surprisingly fun and the ''incentive'' certainly helps it is short but sweet and that going for that 100% completion was a good…Why it fits
Check it if you want action, casual filtered by relaxing, single-player.
