Amazing. Love the polish, graphics and atmosphere, especially that dithering shader, it works very well with the shadows and the trees. The park is really beautiful!
Biggest issue I had - the game seems to have a lot of invisible walls. Either some world geometry isnt quite right, or some bushes or other blocking obstacles dont display properly, or have a mismatch of some kind with their visuals. Its especially frustrating when you try to escape the hedgehog god and the most obvious path away is blocked that way! it also makes one of the lamp's switch buttons inaccessible.
Another issue is - dying during the hedgehog-finding phase seems to reset the whole game. It really should just put you back at the start of the hedgehog finding phase instead, playing through the whole setup again really kills the games' momentum I think.
All in all an extremely solid entry, the best ive played so far.
