Very nice usage of the theme and limitation! I kept dieing on the second double jump over the moth (because I didn't have enough power), until I finally figured out that you need to use the slide mechanic to gain power hehe.
I think it was obvious enough - it felt good to see the power bar fill up once I tried doing it. I think the average player would probably like a little more guidance, but I know it's hard to make those things in such a time crunch. It's something I should have done in my game too.
