Not worth the effort!
the game play was kinda fun but you have to play on hard to to see any nudity and the nudity isn't worth the effort that the hard difficulty requires. if you do another like this i would suggest a massive improvement in the reward you get for beating the game on hard like a gallery or an actual sex scene, anything to make the effort worth the reward.
Make it easier!
I'll never play Metroid the same again.
The difficulty settings was a nice touch.
Putting in difficulty levels was an excellent plan.
There is something REALLY wrong with this game...
unlike many other hentai games... I enjoyed the gameplay more than the hentai O_O no, next time don't make the gameplay worse, but the hentai better XD (I'm not joking about that -_-U)
