I appreciate you taking the time to play it!
I definitely think there is a learning curve that could be better explained in-game, in the opening, or via a tutorial.
The only clears that count towards building up your supply or scoring points are the targets (or “pegs”) and you are discouraged from destroying regular blocks just for the sake of destroying them, as they only waste your supply.
Again, thank you so much for taking the time to play it and provide some feedback!
