Hey guys!
I don't have any github accounts so I wanna to write about some suggestions for Tic-80 right here.

1) write/read from/to ".txt" files, to make some editors in Tic-80 (level editors, ZIP converters, graphics editors, vector editors, text editors etc)
2)  no "Close Game" menu for .exe

3) more layers for graphics: Fore, Middle, Back layers would be an awesome (in the current moment we have two layers: TIC, OVR, it would be an awesome to have BCK layer)
4) 64*64 pixel mode to make more low res games
5)  I have one more suggestion: Custom Sprites for fast draw, just for example Unzipped Custom Images.

          "local MySprite = new CustomSprite(array);" - init of custom sprites
          "cspr(MySprite,x,y)" - fast draw of custom sprites (more faster than pixel by pixel drawing)
          PS ( Awesome for: graphics editor, unzipped images, big bosses, scrolling backgrounds
            without taking up space in regular sprites place)
