The randomised tile placement is a fun mechanic which leads to an addictive game loop.
However, it also leads to this situation where I had nothing but trees for many tiles in a row, filled up all the spaces with trees, and got game over with almost no score.
Perhaps a way to make the chosen tiles play nicely with the current placed tiles? Because in this case there was nothing I was able to do correctly with only trees, with no possible places to connect 3 trees together. I guess I was unlucky for the whole map though.
