This editor has potential, i mean you got the base: making pixel art, saving the files to .png, the concept is there but the editor itself is kinda.. Empty, heres a small list of important stuff you should add:
- be able to select the pixel art size (32x16, 8x8, 64x64)
- add a fill bucket tool
- change the color bg to some nice tiled squares like this
- add loading files in
- zooming in / out
