Well sure. I understand the limitations extremely well. And making a game like this in a better engine would be preferable. The reason I'm making my game is to help keep this engine alive and show what it is still capable of for new developers who want to try something with it.
The reason I ask why you're making a remake of "Hellwomb" is because Hellwomb is someone else's game. Plenty of games get fan-games, especially FNAF. But since Scumhead is a much smaller developer, I would just recommend that you ask Scumhead if he'd be comfortable with you making a remake before doing so. Unless you already have.
