Castlevania was actually the initial inspiration. I stopped trying to clone it a long time ago but it still inspires me.
The moving vs. attacking thing is a good idea balance-wise and it fits with what I'm going for.
The graphics are all placeholders. I might want to keep one or two sprites, but I want some actual art. I'm no artist, and I can't seem to get an artist to stick around.
The goal is to make a game based around a specific kind of movement, you could call it a gimmick but as far as I can tell it's never been done before. It also lends itself to certain other aspects of the game, such as how weapons and upgrades would work. It's hard to code for the movement I have in mind with out sprites and animations, and again I'm pretty hopeless at making them myself, and I can't find what I need anywhere.
Thanks for the feedback.
