The controls are somewhat realistic and difficult at the same time, which really makes this a great construction puzzle. Unlike others I've played, this one uses an interesting angle system, making it harder to move and position the pieces. I gave it a 4 out of 5.
It does not lag here, it is actually very smooth. The music is indeed bad and needs to be changed or removed. I do not see a problem with the life system as this is an easy game.
Not a new concept, but still very well made. The background is good and matches with the maze itself. Ths higher the level, higher difficulty, although I found it pretty easy. Good game overall 4/5
