This is such a great (and addictive) game!
Alas, I'm quite rubbish at it - so my best was only 127 or so.
But what a lovely, original idea here.
Also, the music is quite good, but I had to play on BBS to hear it - as didn't play audio on Itch
(might wanna check the BBS for help on that - as think newer HTML templates fixed this for Chrome/similar browsers)
Well done!
