The Perfect Speedrunning Game

You need to move to collect the blue orb, and possibly go back to collect an orange orb, depending on what mode you selected.

Move with WASD and jump with space. You can wall jump.

"Play with one" means you have to collect a random blue orb, and don't have to go back.
"Play with one back" means you have to collect one blue orb, and then have to go back to where you come from to finish it (There's an orange orb where you start).
"Play with all" means you have to collect all 16 blue orbs, and get teleported back to where you started.
"Play with all back" means you have to collect all blue orbs, and navigate back to the orange orb.

The blue orbs are visible through walls, but only if you're standing still.

I can say with 100% certainty that the game is beatable.
