A 23mb (while compressed) pixel art game?
With a very decent amount of content for its size?
God damn, I'm sold.
You don't necessarily need to get Game Overs to unlock the monster sex animation, instead, you gotta get lucky when you kill one and receive a special item from them. In the case of bosses, they ALWAYS drop upon killing them.
I am so used to games including escape options by spamming Left/Right - A/D, that just holding Z feels weird.
If I have one complaint with the game, it's that your healing items aren't multi-use, and sometimes you end up with no MP because you used the Sniper Rifle so much, and that shit takes a lot of MP per shot. But I'll just chalk it up to personally being terrible at maintaining a good MP level.
EDIT: ALSO! The gallery is open right from the start, you just have no animations unlocked because you need the monster items.
The gallery is accessible from the MAP menu, the game calls it the EXTRA stage.
I think many other platforming/side-scrolling/adventure H-games could learn a lesson from this game, IMO the animation unlock system is great, even if Game Overs don't get their own special scenes, that's fine by me.
