Interesting idea, having to play Tetris while also avoiding the falling blocks. The controls were a bit tricky though - have the W/S keys control the player while A/D move the blocks led to me getting my wires crossed a bit. I’d suggest using WASD for the player and the arrow keys for the blocks (the game probably doesn’t need to be first-person since it’s on a 2D plane).
Still a very novel concept; I’d definitely recommend trying to see how much you can improve on this idea because I think with more polish it could be really good fun!
