You got a pretty interesting game going on here. I liked the idea of the ants helping the queen ants and the graphics were not too bad. The gameplay mechanics were quite difficult though seeing I had limited space to work with when making the bridges and the physics almost always messing up the structure of it. Overall though, this game was a pretty nice entry!
Also, for some reason when I begin a new level and try to restart, the space button doesn't work the first try :c
