Others - KEMOMIMI TREASURE HUNTERS! [Acid Style]

Really fun game with great pixel art (which is drawn large enough to enjoy) - the twin mechanic is great and fun to play around with, and combat never feels like too much of a grind/drag. Like someone else said, it's fun to let your NPC follower (the other twin) just get trapped/abused as there's no consequence for them, only for you (which is useful in a gameplay sense too).

Nice gameplay focused around setting up traps between you and your enemy and fending them off. Direct your AI partner to either stay in one place or follow you. Never played anything quite like it before.

The H animations are cute, and your AI partner has limitless health, so if you please you can tell him/her to stay in a vulnerable spot and get milked without consequence.

Not yet translated, but watching the demo video on DLsite for the basics, and just doing the ol' talk-to-every-NPC routine got me though the whole game.
