This is a very good game. Good models, quality animations, everything we're looking for to beat the meat out of you.
But there are a few drawbacks
The first is duration. In my opinion, the game is a little short, and could have lasted an hour longer, with the addition of a few Harem scenes.
Progression isn't complicated, but it's a little vague. The map isn't large, and there are only 3 characters to romanticize, but the clickable zones to change zones are a little lacking in evidence (I'm talking mainly about the kitchen).
I couldn't figure out how to unlock the last scene of the game. I had to play for 10 minutes, repeating over and over what I'd already done 15 times, before the game said “Oh yeah, by the way, the last scene is available”.
The game's engine is a bit poorly chosen. I'm not a developer, and I don't know how complicated it is to learn a new engine, but even if one ( 1 ) passage justifies RPGM, the game could have been a touch smoother with Renpy.
Once I'd finished the game, I'd have liked the dialogues to talk a bit more about the harem situation in the house, but no . Hardly anything.
And the pace quickly goes off the rails, and the corruption moves a little too fast.
Fortunately, the characters are sexy (especially the nerdy girl).
I'd still recommend this game, it's quite short and well worth the effort.
