Weird game, exactly like the challenge, which I didn't knew existed until now.
I don't feel there's any control when the difficult is increased. The crowd just through rocks to me and I just fall. Can't balance with the arrow keys, jumping or standing still. I could only pass through the crates on lower quantity of them, but on the top level with just 1 point of difficult increased, It's just impossible.
I guess it's just like that challenge lol
Even though, the game is still playable and kind of fun. Maybe with some tweaks you can do a port on mobile, where I think people would download and play.
Also check the sfx volume control. The crowd sounds too loud.
Nice job! Congratulations!
