Really fun game! This is already my favorite Tetris game and might actually end up being my favorite roguelike!
The block clearing being manual feels really nice, and I'm glad you can't accidentally delete yourself anymore!
I love how you have to balance the tetris line-clearing with getting potions/treasure and not get overwhelmed by enemies. There were definitely situations where I put a block in a worse place than you'd normally put it in a Tetris game since I didn't have the health to fight the enemy inside of it.
Only real bug I've encountered so far is where in the endless mode, the game freezes sometimes when it tries to pick a new Tetris piece to spawn, which is kind of a bummer when it ends up ruining a decently-going run.
I'd love to see expanded roguelike elements like gaining random abilities/perks, as well as different player classes and more enemy types!
Also, is there a way to spend coins? A vendor would be nice. He could even spawn on a rare Tetris piece variant!
