Thanks! you should be able to use all 10 balloons to reach the bottom. The key is using the glowing clouds to find your path, which could surely be more pronounced if I had more time.
Yoo I did it! But about 10 minutes ago I thought I found the end, and if that had been it, it would’ve been a crazy good cinematic ending. But then I played it one more time because your comment said 'follow the glowing cloud'and then I found the REAL end! It was amazing!
But the other thing I found was also way too good to just be a bug. Let me explain: I was at the rock with the little crack in the wall, and when you press the left arrow there, you're able to move a little bit down so you're able to get through the crack. I was there twice and thought ending on the big rock was the actual ending. But no! The second time, I dropped down on the left side and managed to fall with 7 balloons into the depths. Then the background went completely black, and only my 7 glowing balloons and the wire were visible. It was SO cinematic!
The whole game was cinematic to begin with. Thanks for creating it! Some sad, atmospheric music would match this game crazy well. Maybe you could add my bug as a second ending, or maybe it's already a secret end? Either way, awesome game you created there!
