Just checked out the end with the cheat, that's great. Love the little details you added like the bunnies holding glow sticks, awesome work.
Main things is that when the power board and plug are near each other its tricky to click on the correct item, especially if they get hidden behind the hedges. I was also thinking that mapping these to buttons on the keyboard could help but saw your response in the other comment.
Others have also pointed out maybe background music for the main game would add to the atmosphere.
Overall its a great game and think its cool that you added extra powerboards and the cheat code so everybody that wanted to could enjoy the ending.
