Perhaps some more thoughts on my part about the stress bar: I would expect that I loose the game when it is full, so i was a bit confused when it was full and nothing happened.
And a bit on the controls: the jump itself seemed not high enough to get on the platforms but near platforms the jump was higher. Maybe the intention was that the player climps up the edge. But without some animation thats a bit confusing.
I hope that helps to understand what went through my mind and you can use it to improve.
Nice idea with the different endings btw.
