Hi kristiangitar! I'm a big pokemon fan, and I liked the idea to mix it with a medieval-like theme. ^^
I agree with what wolf said, the movement is a little off from what you'd expect from a RPG. Also, using some pixel snap would help align the pixel art graphics so they all fit the same scale, which looks nicer. This might be very early in development, so you might have not worked on it yet, but I'd love to see some variation between different places, like maybe a different color scheme or different building types between the starting town and the second one.
As for game design, I can't really opinate because the game kinda glitched on the first battle ^^; so you should get to fixing that before anything else, if the battles are going to be the main gameplay focus that is.
Hope this gave you any insight. Wish you the best! :3
