I think this project definitely has potential! The inspiration is very blatant but I think that's fine if the execution is good. Though there's a few big issues that need to be addressed before any new chapters come out (in my opinion at least, take these with a grain of salt):
-Please just enable saving anywhere. There's no reason for a game where you look for vore scenes to have fixed save points, it'd be such a nice quality of life change to just save whenever you want to come back to scenes whenever (I know there's a scene viewer at the end but I much prefer just keeping saves and seeing scenes organically).
-The maps need to be way smaller, the whole school is so massive and all the rooms are large too with only 1 or 2 things to do in them. This is especially a drag when you get a key to... Some room, somewhere, god knows where, and have to go look for where the door showed up. Tighten up the maps and add labels/landmarks to doors so it's easier to navigate the game.
-The combat system is very flat and uninteresting and IMO doesn't even belong in a game like this. Fighting some spirits but just being instantly eaten by others really doesn't make sense. If you really want RPG combat that's fine but at least make it more cohesive with the rest of the game, have more vore-centric mechanics to combat like enemies eating you and having to struggle/coerce your way out or something.
Overall there's a lot to enjoy here, and with some tightening up I think future chapters could be super super solid. Looking forward to more!
