Your cat Lorentz got lost in space! Find and rescue him, fighting depleting energy, avoid (or destroy) asteroids, get powerups on the way (watch out, they deplete quickly too!). Watch out for Lorentz forces when moving in electromagnetic fields and use them for your advantage. They try to balance part of your speed perpendicular to radius at any given moment, so if you fly into it at just the right angle, you will orbit... And at other angle, you may gain lots of "energy-free" momentum.

First levels are a tutorial (and sadly only one more simple level is playable), but if you somehow miss it, the controls are:

WASD - movement
Q E - rotation
Space (no pun intended) -  laser
P - pause
