This a pretty decent online Tetris clone!
The rotation feels a little off, it's pretty obvious it's not the exact same rotation from modern Tetris games. I also know know if I just had insane RNG, or if there's no normal L piece and no inverted S piece. There's inverted L and normal S, but I couldn't seem to get their flipped counterparts?
But again, pretty alright for an online Tetris. I dig the minimalist style. It kinda reminds me of like weird Flash games I would come across at like 1 in the morning as a kid. Especially the sound effects. That's not a bad thing, I personally like it. Though I can understand why other people would dislike that.
