Confession time: Classic Castlevania kind of pisses me off.
-I've always hated the stair climbing mechanic in all of the classic Castlevnia games. Stairs are essentially just an incline, so why don't they just function as slopes as opposed to an object you have to interact with that limits your mobility?
-Why, at all times, do Classic Castlevania games show "Enemy Health" in the HUD? At first I thought it was simply to display the HP of the last enemy attacked. This makes sense. But then I learn that it's actually the health for the end of stage boss.. Um, why is that even there? It wastes precious screen space for no practical reason and honestly seems like it was a bug they never got around to fixing. Why doesn't the boss' HP just display the moment he enters the screen, similar to the Mega Man series? It's nonsensical.
-I think the "Fake Trevor" sprites from SotN / PoR that everybody loves looks ugly as sin. The entire thing is ridiculous. For example, Trevor himself shows so much thigh that he puts the succubus to shame. His idle animation where his fists are raised like he's ready for a street brawl, don't quite seem to fit aesthetically with the dirty, barbarian rags that he's wearing.
