I'm sorry, but I just don't quite understand what the concept here is supposed to do. An extra platform gets added on each death making the course longer. And thats about it from what I can tell. Dying doesn't really interact with the actual platforming in any way, or change how you approach it. Its just the same, but now its longer. And I can't really find any fun in that.
That being said, you managed to make a game, with functioning platforming, some interesting visuals, and actual audio. And that in and of itself I think should be commended. You now have more experience to improve your games in the future!
I didn't really understand your game. Still, thank you for making it :)
