For some reason I didn't get the notification for your question but for some reason I ended up here again.
I've watched the video and I can do the things you did, but I didn't know it was possible. Like pushing in the small obstacle.
Thanks so much for the feedback! I'll definitely work on a better explanation of the mechanics in the future :)
Hello, I've uploaded a hopefully working version of Ice Canyon now. Give a another go if you'd like to :)
