I like the idea but execution could be better. Here are few advises: decrease falling speed by 50% to make it easier to control character in the mid-air, add some checkpoints and change the way the pink jump things work. I'd make it this way: add a variable that represents number of jumps available to the player. It's default value is 1 and when you land that variable is reset back to 1. When you touch pink rhombus extra jump is added automatically to the jump counter. Keep up the good work. Cheers!
