Long, but not difficult (and guys, pixel hunting is when you need to click something too small with a mouse cursor that doesn't change shape - the artifacts here are clearly evident when you see them and catching them is easy). Loved it, like almost every other GregoryWeir's games. Takes quite some time, but it's time well spent.
Beautiful game but needs a better implementation of the gate missing detection, sometimes it's really painful to see your multiplier get halved for apparently no reason as you weren't even on the screen.
It gets boring quickly. The plot fails to keep me interested and the funniest level is the last, where it's tricky to pass to second platform. I'd like it better if it has a more precise crate-shooting system and better levels, where the fun doesn't come from "spam boxes and see what happens" or at least where the player isn't tempted to shoot everywhere disregarding the crate count.
