Heart Box - physics puzzles game
Heart Box sends a small robot through Professor Rat's experimental rooms, powered by twenty physical toys: trampolines, dynamite, conveyors, fans, portals, lasers and the occasional dynamic saw. Each room is one contraption-riddle between the robot and his charger.
The physics are consistent enough to reason about and silly enough to enjoy being wrong about.
Tip: activate nothing until you've traced the full chain in your head once — half the rooms punish the eager finger with a robot in the ceiling fan. The science games tag experiments further.
