This is a new platform game with monster girl hentai elements that's coming out in June. There's more information on the developer's site, including a demo.
It's a platform game where you play as a security guard. There's been a lab accident and lots of genetically engineered monster girls (the MoGi of the title) have escaped. They're horny and want sex with everything in sight.
From the demo the game plays pretty smooth. It's a mix of jumping, solving the odd button-press puzzle, and whacking horny monster girls over the head with a trusty wrench.
If you happen (or choose) to be a little too negligent in swinging that wrench, then the monster girls will knock you down after a few hits and there's a sub-game to break out of their sex attack. Fail (or choose not) to break out and you get the Game Over coming scene.
|My, what a large pair of...pumpkins you have|
I think the MoGi used in the game are part of a card game (similar to Magic: the Gathering or Yu-Gi-Oh, but without the collectible element) created by the same people. I couldn't find out much information on that so I don't know if it's out, in development, to be released as a tie-in for the game, and also whether it's "clean" or sexed up like the platform game.
The game looks like it might be interesting, although the cartoon style of the artwork might be a little off-putting in an eroge for some.
