It was a nice game. Some comments. 1) Found it difficult to use both keyboard and mouse at the same time, especially as need spacebar and arrow keys (2 hands) + mouse buttons Could use alternate keys like up for jump and ctrl for change dimension etc 2) Voice was too soft, can't hear properly over the music. 3) Player can get stuck in certain scenario when the dimension is switched. 4) Player slides off the ledge if it is near the end. 4) why the need to press mouse button at the door? can just move automatically once reach the door 5) The pen and paper concept was well done
