Cute start, reminds me of games like LightBot and that one mobile game I cannot seem to remember the name of which I would really like to play again.
I like the idea of the "instruction pointer" being an object in 2D space, but unfortunately, it doesn't really matter much at the moment. Adding some constraints or Zachtronics-like optimization challenges here might be interesting? Tutorial and UX could definitely be better, needed quite a while to figure out what was happening. A way to move stepwise would also really be appreciated
Apart from these issues, I'd love to see this developed further, I'm a sucker for this kind of game. Also, as always, props to anyone who doesn't use one of the big engines and decides to make a game from scratch instead.
