This is the kind of indie game that puts me at risk of losing sleep. I love it, even if it sometimes makes me feel as though I have impossibly bad luck. I'm glad you added the Tactics Mode.
It's funny when you get those long, weirdly shaped pieces and they somehow have not a single place on the board where they fit usefully. I find myself wanting a little bit more influence on the board, a way to occasionally nudge things in my favor to prevent those frustrating situations where you felt like you were so close to having a good move. This game is either very satisfying or deeply unsatisfying.
