Reminds "Superhot" a little. Some objects look interactive, but they are not, so that is a bit confusing. You can try to use colors to navigate the player, like in "Mirror's edge". For example, the path may be yellow and other non-interactive objects - white. When you die, it doesn't reset your age. How old should I be to die?
Good job :) You can try to add coyote time to platformers and build the level using metrics. Sometimes player has little room to movement or has to go to the beginning of the level to overcome an obstacle if he fell. That's difficult to do on Jam, but if you have more time, it will be great to try these new things.
