I left this until last at it's the only entry that needs to be downloaded.
I really like the idea of playing as Laika and the first person 3D is very well executed.
The TV in the corner was a brilliant touch.
No support for the arrow keys though which can be a big problem for left-hander like me, especially when the jump key is space - my thumb is on the wrong side to press space when using WASD (left hand is using the mouse).
Would love to see a longer version of this maybe with more training for Laika and a longer period in the space ship, although we all know where that ends.
