Oppaul - Lumile the Pure Maiden ver.1.1.0 (eng) - Adult Sex Game

Machine translation

An RPG focused on ero events. it contains no combat, no levels, and no money.
Proceed through dungeons by avoiding enemies,
and see if you can find the unicorn's "power" that lies within.

You have an HP bar, as well as a Hunger meter,
which will significantly hamper your move-speed if it reaches 0.
Use lots of recovery items to stay in tip-top shape.
Note: Wandering around town will slightly increase Hunger.

Your next objective is written on the menu screen in case you get lost, and need help.
