This was cool. I like that the game wasn't over when you found the blanket and the level was nicely designed to take into account the new mechanic with blanky.
Something that could do with some post-jam tweaking is the gliding part. Even if I didn't want to use blanky I had to which made small, quick jumps tedious (eg. climbing back up the rung things). Perhaps a ray cast downwards to detect if there's ground there and if there is, don't pull out blanky? I don't know, you could probably think of a more elegant solution than that haha
Anyway, I enjoyed this. Nice voice acting (especially the "oh come on!" haha) and peaceful music. Well done!
