Great game

If you like Upgrade / Bullet Hell you may also try Nebulock, it's great https://www.incrementaldb.com/game/nebulock7

(idk why it's still not accepted, it's 80% like this game, are rocks a definitive enough feature to make it not incremental enough?) (edit: apparently the Upgrade games are questionable, we'll be lucky if we get upgrade.incrementaldb.com in half a year)
