Yay, a fellow Picotron entrant! 🤓🤜🤛🤓
Enjoyed this one - especially as it kinda reminded me of one the earliest games I can remember playing ...Joust (on an Atari 400)
I thought for a while that I'd found a bit of a "cheat" - by moving as fast as I could across the wrapping screen, so that I could try to beat the collision detection. I managed 49 secs doing that - but your detection code is very good, even at such speeds!
Nice one! 👍
