There's a lot of problems here, but also a lot to like. I like how the mechanics increasingly get more difficult and trying to mentally juggle what all the directions mean is really fun, but the timer is not nearly strict enough for there to be any tension while laying down the blocks. Laying down blocks itself however is oddly satisfying. However I can't help but feel that it would be much more satisfying if the timer was extremely strict and you had to input the commands supper fast. I also think the ball should roll faster as right now it is slightly boring to watch as you want to just move on to the next level. I think the slow rolling speed would be a nice reprieve if the block placing part were a bit more demanding, but as it is now I don't want to have to wait for the ball to roll before I can keep playing. I also feel that making the directions transparent is basically a non issue and thinking of a more interesting mechanic to introduce at the end would have been a more sastisfying way to finish the game with. I don't want to try to sound mean, I only go so in depth because I can only imagine how fun this would be if it were just a little more fast paced. This is a solid foundation. Great Job.
