A complete bare-bones experience, not any different from the vast majority of mediocre RPGM games out there. What I appreciate from the game is that it doesn't waste your time by creating massive maps and placing some NPCs here and there with pointless one-liners and no real gameplay element linked to them. There's literally one merchant and one guy you talk to. And a short walk from the guy's house to the dungeon.
The gameplay is the usual trite RPGM affair with physical attacks and magical attacks and no real novelty in how the combat takes place. It's not winning any awards in this department. I always like battle fuck in games though and that's there so it's nice. Unfortunately, it's the only H content in the game I think. Apart from a few clearly marked "suspicious mines" on one of the floors and a chair on the 11th floor which you apparently can't interact with as it stops you from completing the game (there's some discussion on this on the thread, I didn't interact with it lest anything untoward happens). Unfortunately, making the only H-Scenes in your game being ones that need the player to be an utter moron or just sit there waiting for the enemies to start doing their H-attacks is one of the most deplorable ways of adding porn to a porn game. Might as well just have an option at the start of the battle that says something like "Wanna fight or watch the goods?" so that I don't have to suffer through the tedium of RPGM combat and the RNG before something titillating finally happens.
The character art is also hilariously mediocre. Kudos to the translator though for not only doing a great job at translating the game but giving a lot of helpful tips, hints and images to overwrite the banal vag-less protagonist portrait. There's some jank in terms of the dissolving clothes attacks that if you repair them and an enemy attacks immediately afterwards dissolving clothes again, the character portrait doesn't update and stays naked until the next turn. Weird.
Poor game. Not worth the hassle, imo.
