This is a quality adventure game. When I finished I thought the ending was well done. The robot has served his purpose, it's only logical to shut down. I love the interactivity, the sprites, the animations and the setting. You show some real promise. I hope you'll flesh it out more after the jam or work on a new fully fledged Adventure game.
One nitpick: I would seriously rethink the time limit. You may be suffering from developer familiarity. Consider this; why would you want to limit the time people can spend appreciating your game?
