Great game!
I really struggled on the last two levels. The method for the final level was to slide the egg slightly without it breaking.
You seem to describe being able to stick a board into a wall as a bug, but I honestly couldn't have managed without it. In fact, I think it's a pretty interesting mechanic for our first boards.
Anyway, the game looks great, the gameplay is very interesting, and I had to come up with a whole bunch of strategies to get through each level. So congratulations!
