Premise
Shou was a NEET in the human world, wasting his life until at last he was disowned by his parents and drowning in debt.
The solution was of course to start managing his own dungeon. 🙂
Sim Game
Treasure Inside! is a dungeon management simulator with pretty much no tension whatsoever.
Collect various items and decide where to lay traps and monsters, which you raise yourself.
Create the your ideal dungeon and upgrade to give the heroines the best punishments.
Event scenes and attack scenes can all be skipped.
H scenes can be ended at your preference. You’re in charge. Have fun!
