NOTE: "PRESS TO START" on the title screen is actually a button you need to click. I didn't notice how poorly that read visually until after the deadline.

This is a pretty standard platformer. Collect the keys on each level to open the door. But your countdown timer is you: you're an hourglass that flips every time you jump, resetting your sand just like a real hourglass being turned over. Jump when you're almost out of time and you'll get a big refill. But jump again too soon, before much sand has run out, and you'll waste most of that gain. Some stages have low ceilings where you can't jump without bumping your head, so plan your flips carefully. Run out of sand and you lose. Collect the keys, make it to the door, and keep the sand flowing. The sand must flow.
