Heya thanks man :) Yeah the sprite assest may not be top notch :D The RPG part is not fully developed yet, i think that you are going to like it when i get further on wuth the whole system :). And then not everyone can like everything so that is fine :)
I will add specials giving you the possibility to aim those enemies on horizontal scrolling parts too ;)
I am working on it as im typing! I hope to release a new version of it tomorrow :)
Thanks again! :)
