Hmm, I think I found a broken Critter improvement. I finished the game without getting to the last kicker, just by investing in the bat-gang to max it as soona s possible. You might want to check the frequency of those batgangs.
Anyone else noticing a weird hiccup recently? First the game slows down for a fraction of a second, and then you're running alone, with all your infected horde just vanishing?
Getting stuck on 10th level with the pink horizontal bar, can't make the shadow jump high enough to clear the other end, no matter what I try. Otherwise an interesting game.
