Bump.
I was bored, and I couldn't boot Penguin Brothers properly, so I made a testrun of this game. You can see it here:

Sorry about the low quality of video, that was the best I can do.
I didn't try hard to optimize, so it's very suboptimal.
Here's some explanation of this run:
1:02 - this wall climbing isn't supposed to be possible, but I made it by glitch. If you cancel walljumping right before he turns around, you can climb a bit higher.
1:15 - The game slows ifself when you run beside wall in early part. Landscape viewing disable this, so it saves some time. I mean, it should have. For unknown reason, the game still kept slow after using this trick. I think I had to switch the view during wall running.
1:25 - I rolled before cutscene to step further.
1:39 - Being in water slows me, so rolled to gain more speed.
1:42 - Obstacle can be removed by stepping on it.
3:19 - a well-known shortcut.
