I could only beat the first level and only after more than a few tries. At first, I was a little unsure on what should be happening. The instructions on the page were a little unclear. Putting them in game during play might help a bit.
I think the biggest frustration for the game is the slippery controls. I understand the need to make the game a challenge, but this felt like taking control away from the player and made a loss from falling off the edge feel bad. Also, if you're using Unity's collision system, I would recommend shrinking the big cube's collision mesh to be just inside the cube instead of exactly on it. Or do it for the player. This makes close calls more survivable and exhilarating for the player, especially when cornered and you think you're otherwise doomed.
Overall, congrats on making this for a jam. I liked the premise of needing to hit points on a map before being able to permanently elude your pursuers. Be proud :)
