Commander Keen: Robot's Revenge!

Description
Commander Keen: Robot's Revenge! is a fan-made game based on the Commander Keen series. Keen has been kidnapped by nefarious robots and must now fight his way through the robot-controlled space station. For defense, Keen has his trusty gun but ammo is limited and must be collected throughout the levels.
This side-scrolling platform game controls similarly to the original games, complete with moving platforms, poles to climb, and switches. Later levels include underwater levels, and levels where Keen rides a motorbike.
