I'd just wish it would be more consistent. It makes no sense that some jumps are mere pixels (exaggerated) but especially when you're going slow you get screen filling ones (NOT exaggerated).
Or how you get sometimes dozens of tunnels in a row and pick up speed that you could jump over the alps and the next run youre only getting reds...
In level 8 you can get the cat stuck on the right zig-zag when you send it down the left and pull it all the way up with the yarn and go down right afterwards: its simply grows to fat.
Game needs a visual cue to what you're supposed to grab at the current stage.
ie...
Blue px: should already have
Green px: Get it now!
Red px: No way, José!
Now, the new ending IS realistic:
Oh, hey, we send them to a parallel dimension, the logs state they where mentally transformed by a foreign intellgence and one man blew it all up. He must be a nutcase!
