Nice to see a fresh tetris map after all these years and good work on your first map.
There could be some tweaks like not spawning too many grunts at once and and orientating teleports so you face the right way when you come out.

Overall nice map and can be played solo if you don't mind a few deaths.

There's a few parts I was confused by but overall I enjoyed it :) thanks hope there's more to come <3 nice seeing Tetris again.
