I'm the solo dev behind TwoGrid Blocks, launching Tuesday. The core mechanic: you control two Tetris grids simultaneously one thumb per board, both dropping at the same rate.
Building it, I discovered the hardest design challenge isn't the code it's tuning the difficulty curve so both boards feel equally demanding. The moment one side gets harder, your brain locks onto it and abandons the other.
TwoGrid Blocks is a Tetris variant with a twist: you control TWO independent grids simultaneously. One thumb per board — both drop blocks at the same rate.
The mechanic sounds simple. It isn't. As speed increases, coordinating both grids becomes genuinely addictive chaos.
