Okay, so imagine Tetris, but with Sonic characters barging in to mess with your game. You're stacking blocks like usual, but if you clear two lines at once, Knuckles just punches through a random row like he owns the place. And then Dr. Robotnik shows up uninvited to blast chunks of your stack with missiles—helpful or annoying, depends how badly you were relying on that setup.

Controls are simple: left and right to move, up to flip. Sometimes you're controlling Knuckles instead of the blocks, which is weird but kinda fun once you get used to it. It's chaotic in that classic Flash game way where you're never quite sure if the "help" is actually helping.

Definitely one of those "wait, why does this exist?" mashups that somehow works.
