This is a fun tricky-towers style game, but it could definitely use clearer instructions. Starting off it was hard to tell that the point is to stack as high as possible; I didn't know if I was making lines like tetris or matching up numbers or colors. The game breaks if you drop a piece off the edge without placing it, and it can't be restarted once you lose. Most importantly, though, the game is fun which is a huge accomplishment for your first game jam. Congratulations!
