Impressive how much there is of minesweeper in this, given the tiny code size, but it would still need a bit more to be nice to play.
What were the self imposed constraints ?

Also, there is some bug with the counting in the top left corner :

But you're likely aware and the code size is more important than full correctness, I'm guessing.

Thanks, this was for tweettweet jam x so had a strict 500 character limit (and I was rushing a bit at the end since I was trying to fit as much as I could in the limit at the very end of the jam). Definitely want to come back to it and add more features/fix issues with it; and hopefully some how keep in under 500 characters :)
