Oh, that's a neat idea - like sokoban, but you also have to keep in mind the distance you can travel, and can't view the entirety of the level at once. Makes you notice the presence of timer at all times.
Cool visual style, though the blurry text stands out a bit.
There was a bug where I was able to drive through a box, and then get it stuck underneath me (Windows version), but that didn't ruin the level.
Great level design btw! The levels felt "just right" - hard enough to pose a challenge, but not hard enough so I would get stuck.
Sad there was no audio.
