I think a map would actually take away from the experience.
if there's a marker on everything --like in Skyrim-- what's the point?
Well, its a hentai game so I'm not too concerned as long as the animations are great.
I'll disagree with 2/3 to 3/3 points

- Think the old Castlevanias. Or RepureAria. The map doesn't need to tell you "hey, there's a secret here!". Like, the door gauntlet with the red-eyed invincible ghost can be left as a "?" in the map, as a whole. Doors hidden because of technical shortcomings, which could be otherwise be perceived as a "tricky, but good idea" gimmick, with a map hinting another exit exists in this room. No more, no less. Specifically, referring to this helpful post;
Edit edit: Fuck. It was behind a door in the hallway with people cumming on the walls. I was so distracted by sharks and the obstacles I completely overlooked it. Damn.
- Skyrim is highly customizable. Given the mind-crushing scope of the game and map size: 'more' is better than 'less' - underwear naturally excluded from the argument. This is still too much here, yes, considering this game is not a 200+ hours game. A plain, simple Castlevany-esque map'd be enough.
- 100% disagree with the last point. A game is a game, an OAV is an OAV. If you don't have the skills to do a game, just relase an animations pack to fap to. But games are more than that, with much higher potential. Dev has talent and great insight on 'how to make a game?'; this talent would be wasted on a random OAV. This is a decent+ game, before any ecchi is involved, we should encourage devs to aim higher, all the more so when they actually try - this dev certainly did.
