I always thought Schrodinger's Cat was unlikely to take being trapped in a box lightly...
You must travel around the inside of the box, trying to get to the node which will collapse the parallel dimensions in the quantum state to a new reality (I wasn't really paying attention in physics), searching of the exit. Interacting with other particle will gradually collapse the quantum state, leading to your demise! Use the power of quantum! "Q" and "E" will alter your size, allowing you to move or become invisible to particle. Arrow keys or WASD to move.
Get the coins/chests if you care about points. Remember, they care about you.
First time competing in Ludum Dare! Was quite the blast.
Hah, loved the intro :) I didn't quite understand why enemies only hit you when you're normal or big, or why you couldn't move when small. Still, nicely done!
The quantum mechanics proving that this is actually one screen does seem like a bit of a cheap shot, but nobody understands enough to argue so it works! The remarks at the top made my day, funniest thing I've seen in the LD 31 games thus far.
You aren't supposed to be able to move while very small. The trade off is you are invincible to the other particles, so you can use that to avoid being hit in tight spaces.
Nice work, but man this quickly gets super hard.
