I guess I'd call Zombie Hunter an action-RPG. I guess it's technically a platformer, but the only real penalty for missing a jump is that you get dumped into a pit with shadow monsters (only identified if you have a candle in your inventory. If they are identified, I think they will also be weaker than the "shadow" forms.). You can only advance to the right if all enemies on screen are defeated or run away, but you can move back left as much as you want. The goal is to get a key as a random drop from enemies to open the door at the right end of the level.
(this is the frustrating part of the game, as that drop is entirely random, so you may have to pace the entire level multiple times. And then maybe when you get one, it will give you a superfluous second key just to troll you.
The RPG elements are strictly that you can level-up and there are shops to buy items. No real in-game plot and it is a linear game (though you get a choice of two routes to play for most levels in the game).
I guess I'll let you pick a genre from that description.
From what I've seen, I guess I'd call Dark Lord an action-RPG. The town sequences are entirely menu-based, but it seems to be action once you enter a dungeon.
