While playing it, a few strange things happened.
1.By falling with a rope from a hight that takes dmg, the animation of the hedgehog was as follows:
*roll over with closed eyes (normal, nothing here)
*stand still and hat appeared again (np here)
*display animation of hedgehog blowing itself with a detonator - happens when your hedgehog dies (although with 95HP after the fall + no detonator appeared).

2.Cake - this is from the map I think (it's at the end of the demo); the cake went downwards under my hedgehog (although it's solid ground) and kept walking on one place under it. Then it exploded.
