Experiment 13

Experiment 12 was a success, it seems. What's next? Experiment 13, where even more deadly hazards await the inmates trying to win their release. Experiment 13 is the sequel to Experiment 12, and plays much the same: reach the exit of each room without dying. As before, the player can run, jump, and wall jump. Grey squares are safe, red squares are deadly. Some stages have arrows that will change the gravity, this time in four directions rather than just two. Changing the gravity may also even cause certain parts of the stage to shift around. There are a total of 50 stages.
