After destroying the barricade I move 2 robots to the elevator (there is no place for the third robot) but nothing happens.
OK, I’ve found the issue - the game was expecting the robot to stop on the elevator door, not walk all the way across it. When this happened, the event that triggers the exit was not handled.
I’ve made a small change so the exit event is handled as expected. If you download the updated version you can copy the Ecliptic executable over the top of the old one so as not to lose your saved game.
Thanks for reporting this issue, I really appreciate that you’ve taken the time to play the game and let me know about the problem.
