for some reason the upgrades in "mass milestones" dont seem to be clickable for me :c im on a mac using safari, i switched to chrome but then the game wouldnt load at all, just a black screen :0 so i went back and kept playing as much as i could in safari, and the parts i was able to play were very fun!
the physics aspect is quite well done and its pretty satisfying to slam-dunk yourself into a pile of particles :P and the minimalist artstyle looks great too!
