Normally, I don't download a game that's so new in the release cycle...but I'm starting to rethink that strategy. Perhaps if I played the 0.1 releases and contributed some valid criticism the dev may take it to heart and improve the game. This game already starts with potential. The story definitely has an interesting premise with real stakes...and it looks like tons of banging to happen.
With that in mind, here we go.
As others have pointed out, the dev needs help with English translation. It's really sloppy at best. Spelling errors, grammar errors, etc. That should be easily fixable.
The second thing is that there's very little variety in the female characters' bodies other than face, hair and eyes. They all look identical. Same size breasts, ass, vagina, etc. That's kinda boring. Vary their body sizes...breasts, hips, ass, etc.
Animations are decent but seemed a little choppy (and trust me when I tell you it's not my PC).
If the story is fully-developed with character development, then that's half the battle. The other half is improving the character models, animation, and English translation.
