I reached the big red hot-air balloon, but I'm not sure if it's the end or no. I don't know what to do next and there's no win screen.
As someone else mentioned in the comments, I didn't realize it was a "rage game" at first, so I couldn't understand why I wasn't going up even though I still had stamina left (the visual of the impulse effect is cool, by the way). Maybe something a bit clearer would have helped. Regarding stamina, I would have liked it to recharge a touch faster at times you end up waiting on platforms for a bit too long for my taste.
