That's an absolute Gem! Short and sweet. The music, the mechanic as well as the puzzle-like solution is what made this game, in my opinion, super addictive. It took me two try in order to complete it, but to be honest, I was able to cheat my way out of a bad decision by jumping on the platform even though they weren't activated. I would be more than delighted to play additional levels in the future, with different stages of difficulty. Also, a great addition to the game could be to enable a free camera-mode in order to understand what's coming up. That said, It's a wonderful beginning!
Cheers!!
