This was short and sweet. I think it needs maybe one more mechanic to link both the astronaut and robot together and create some gameplay beyond just walking. Maybe if there were two robots you controlled and the astronaut could only have four buttons, but each robot has 4 buttons (8 buttons total) and the robots could move them around the map physically and give them to the astronaut? I reckon that would add some fun. Or maybe something simpler like the astronaut only being able to step on each button a certain number of times? I reckon this has potential, good job overall, I hope you continue making games!
