I like your take on inverted tetris, two players always works better than an AI! I'd prefer it without automatic side switching, it's sort of confusing. Found a bug - selecting the next piece with WASD/arrows doesn't work when your selected piece is surrounded by used up pieces.

Nice! Very interesting take on the enemy system -- make the players both the enemy and the player!

Haha, this is a interesting idea!

The switching idea is awesome; I can't wait to play with someone else!

this is cool!

I always love tetris.

Very interesting idea indeed. I didn't really have anyone to play with, but just playing it by myself, trying to cope with the side switches and such was interesting enough.

Visually the game looks quite polished and nice. Controls are good. I can't say that I fully get how anyone is a "villain" in a game like this tho. It's more like you are each other's enemies/opponents.

Great work either way!

It is certainly an interesting take. I wasn't expecting the switch. That was awesome. Kudos!

Fun idea, can't really test it out as I live on a deserted mountain with only a goat to keep me company.
