I love minesweeper a LOT so this is a fun reversal of classic MS. It's a jam game so I can forgive it being a bit unoptimised; the longer i stay on a level/the longer the roots go, the laggier the game gets. Oops! But its got a fantastic ambience. If you ever expand on it, there are a lot of fun plant mechanics you could play with :D
edit: thanks for the message! its updated and runs a LOT smoother now! xD
