> What kind of tuning would you like to see?
It felt like I was at the mercy of randomness in shapes appearing moreso than skill in being able to play the game. For instance, in several of the times I played through a third shape didn't appear until the rows were almost at the lazer, so I was unable to match until then. It feels crummy when you lose to something you don't have much control over.
These are the types of things you find through endless playtesting and having others playtest your game.
