I don't see the connection with UFO 50 besides maybe the similar palette but oh well! Would've gladly paid for this on Steam. I played nonograms on and off on various platforms and all the additions this version brings are excellent. One little qol I kept looking for was the consecutive highlighting of numbers whenever a block on either end within the entire row/column was completed. Really hope a paid sequel with achievements and bigger metagame comes out. Very cool job!
