This game's fine. I'm more posting this review as a bit of a service because the other reviews nor the synopsis mentions that this game shares assets and mechanics- but not a universe, technically?- with Genesis Superbanger Fatal Labyrinth. In that sense it is an even more basic roguelike than Fatal Labyrinth is. Sadly, the soundtrack is nowhere near as good.
An old-school roguelike in the vein of Mystery Dungeon. This is definitely inferior to that series, but pretty decent on its own. The main problem with this game is that it's a little too luck-based in a genre where luck is already a big factor. There are lots of items with negative effects that you can't identify without straight-up using them, for example. Worth trying if you love the genre, but otherwise skip it.
