Thank you! That's sad to hear, but understandable. I wasn't able to playtest the game, so it is quite hard. Though, if there's any part you have a question on, feel free to ask.
[Spoiler for the first room] For the first part of the first room, you'll want to take it slow and have them to stick together and climb together without letting S repel them both off. The second part, you'll need to use S to guide to them both to the next platform.
