There are unfortunately a lot of surface-level bugs still in the build, which I've since fixed; but can't update it yet. The ants are now a bit clingier to the pheromone trail, and I've enabled multi-touch input; but we'll have to wait until after voting before I can get those up.
Thanks for playing, and I hope you had fun! If you want to give the new version a look, after GWJ's voting period ends, I'd appreciate any feedback!
