Dungeon RPG in the vein of Wizardry from Platine Dispositif, a doujin dev who has since gone pro. This is up to date with the latest patch.
Bunny Must Die and Gundemonium Collection are two of PD's more well known games, however their catalog is extremely deep and varied. A lot of it is also not really available anywhere to download or buy. Worse, it's massively underrated. Each and every game they make is unlike anything else out there, go check out the others too!
