Thank you! That's strange, what comes to mind is that the unresponsiveness might be the response to the "electric" platforms. In the game, there are some platforms that are different from the others and are intended to paralyze the player for a couple of seconds. Due to time constraints we didn't make it in time to show that via a different character sprite, and the paralysis doesn't work nowhere near as polished as we wanted to, but that might be why it looked unresponsive.
Thank you for the comment! ♥
