You manage to do soooo many level, and none of them feels like the previous. Some level are quite clever and the player becomes it's own enemy. That's quite impressive. The "Boost" level was quite challenging and interesting to solve. It took me 73deaths to overcome x)
The transfomr parenting on ghost is was a well thought addition!
The game is really well polished, I was also surprised by the quality of the sound design.
