Some suggestions:
It seems like you can only create 8-bit and 16-bit variables.
I think it would be nice if vars could be any size or at least 1,4,8,16,32 and maybe 64 bit would be nice

- It's a little tedious to paint each pixel seperately. I know you can copy/paste but I think it would be nice if you could just select an area and press 1-4 to change the color of the whole area.
- An "undo" button would be great


- Instead or at least additionally to "s" to cancel an action you should be able to cancel an action by pressing Esc I think.
- Selecting an area and pressing DEL should be equal to pressing 4 (white) for this area.
- clicking a tapper while not running will activate the tapper so many times after you click "Run". is this intentional? If it is: I think it's annoying

- "reset" doesn't reset variables
But I'm having much fun with this
