There's all the ingredients for a good robot heist. You have switches, lasers, guard robots, valuable loot, two endings, and robots.
Val (alias: Vertibot), a robot who can only push things vertically, has plans for the ultimate heist. A heist so big that not even the master of vertical pushing can do it alone. Val needs Harry (alias: Horibot), a robot who can only push things horizontally, in order to pull it off.
Arrow keys move, pressing x or space will switch bots (the activated bot will have a red light in the middle), r resets the level, and z rewinds time. You're close to the end of a level only to push a block too far? Pressing z undoes your mistake, so you don't have to redo the whole level!
Some of the larger levels really shrink the graphics on screen, but never to the extent that I couldn't tell what was going on.
