Could use some work, but basically sound
The teleporters were a tad buggy (I kept snapping back and forth when I rolled over one) and the intro was too long. The handling of the Y box was actually TOO good at first (the early levels were boring) but it moved so slowly the even why I saw enemies coming I usually couldn't get out of the way. I perished a bunch of times on level 8 when the big... evil smiley face with prongs thing... kept nailing me in the same spot.
Guess I better start learning Russian...
