I have no suggestions, at the moment.
Also, what program did you use for the art? I kind of want to get into pixel art, but I'm not sure which one is the best for game development.

That's ok. :) I used Aseprite, which is focused on pixel art and I found it to be great compared to other options like photoshop, etc. It's one time payment, very cheap and works like a charm. There is a free option too which is called Pyxel Edit.
