I lowkey tried yours yesterday, I corrupted your leaderboard with chungus 3 times >:3. Anyways, its a really interesting take on classic tetris frfr i found a slight meta where u can place the same type of blocks in the same categories for easy points :3
I think the real meta is highrolling high scoring blocks and spamming them until you reach the obscenely high levels xD The issue with easy block spamming is eventually you reach a level where the speed is just too outrageous and you die. But it was intentionally designed that way, to offer a high maximum value playstyle for good players then a laid back chill style for people who just wanna stack.
