Really nice gameplay but you are not really showing it on this short level.
The pause while not moving is already nice with the theme and let people who are not used to platform to move carefully.
However, the balancing time (left/right clicks) between platforms might have been better with a just-a-little-bit-longer range or at least with more levels. For instance, in a tuto level, forcing the player to sacrifice some of his time to "heal" a platform in order to be able to make the jump. Or the other way around where he needs to "drain" a platform. I'm stating the obvious because the mechanics are great but we did not really need it to finish the level in the gamejam. Ah also, if possible, it might be better to build the game for the web. Downloading files is not the best unless it is from trusted sources.
(I know a gamejam is usually not a place where you have a lot of time, this is only my 2 cents.)
