Very fun takes on Tetris, each with a distinct vibe!
My favorite would absolutely be Forgetris, of which I have already seen a short glimpse on a Bluesky post. I imagined that I would like the forget mechanic, but what sold it to me entirely was the fact that a bit of memory comes back when lines are cleared! What a nice tension there!
Most of the other ones are either enjoyable or clever concepts that would be nice to see developed further. I also adored the absolute alien feel of Sedem Blokov, but I utterly failed on understanding what was going on there ^_^'
