ideas:
- level management (rearranging so you dont need to redraw all the game if you f.e. putted a level too early)
- cloning levels (like to not make a empty default scene but copy tiles from existing one)
- changing title fonts (not only default pixel one, even 3 fonts of current one, serif and sans-serif would be better than only default)
- being able to redraw mobile controls same as sprites in game
- ability to use custom hex color in color picker (right now its limited set of colors)
