Incredible game. Contender for the best on the jam in my list.
Simple yet engaging gameplay, really good sound and tastefull visuals.
One of not so many games i would consider playing outside of the confines of the game jam.
The only problem is that tutorial is too convoluted and requires a lot of reading. I think that majority of people either skip it or start to get bored while learning to play the game. An interactive step-by-step tutorial should take it's place.
Also the final level felt unfair because the whole game you use the whole board to get crazy amount of points and in the end you simply lose the ability to use the center without any prior warning. Not good.
