Good morning!
The only controls are A/D for the red player and LEFT/RIGHT for the green one.
You don't actually need to climb the arms--if you can circle around to the back of Spinderella while it is stuck, you should be able to reach the battery just by landing on it.
Thanks so much for trying my game!
You have my permission to review it, and I'd love to see what else you do in your new video. Please consider posting a link here so that I can see it!
