A great and unconventional roguelike that is challenging even to well-prepared players.
In one of my first playthroughs I got to Anomaly:3 with a score of 4307, and ended up getting defeated by the summoner in there, which not only has proffessional strategy, fully upgraded monsters and powerful healing abilities, but also is at higher level at the player.
Anyway, my attempt to to get resistances from the will o' wisp at the cost of 9K was a bad move.
