So far i love the art and sprite animations are just 101% good i have figured out combat to a good degree although i would recommend for the future Demos to start players off in a tutorial setting rather than mid-end game mainly cuz they wont know what skill dose what ad what items do not to mention the lack of understanding the combat system i figured it out on my 2nd run but still would prefer to play the early game up to or b4 the first boss as a demo as one would learn much more from the first few steps in to the game rather than jumping in to the deep in. Overall right now for me its a solid 9/10 but my gripe is something i know will be fixed so in the future i can see my self giving it a 10/10 i cant wait to see how you developed this game cuz i can all ready see my self sinking in hours in to this game XD.

I dl'd the demo, but for some reason it stays stuck on the "Shady Corner" screen at the start and doesn't load up or something, any help?
