Vampire vs Devil

NES styled PC/Mac/Linux platformer game. The graphics will be exactly like on the NES with almost all the restrictions.

The movement is a bit similar to Contra when you are on the ground, but when you jump, you have 100% control over your moves. You can also decide how high you want to jump. The main characters (Vampire) can do wall jumps. The movement is very easy to grasp, but I want it to be deep at the same time, because I want speedrunners to speedrun this game.
