Nice, we had a similar idea during our brainstorm where you only had 1 ability at a time. Glad you were able to make something around this mechanic!
Design[4/5] Good idea. But I feel the controls could be improved a little. For example by default you always see, when you use arrow keys to move it's always dark and with a special button you can activate your "sonar" to hear the environment. This way it would make less a hassle to move the robot.
Theme[5/5] You have only 1 ability at a time.
Originality[5/5] Not many games like this.
