Love seeing such an extensive response off of this!
I really think this game has a lot of potential to be made into a fully fledged game. It obviously could go well into the theme of games like Getting over it or Jump king, but this one would have a unique take on it by being that you built the entire structure you need to climb, rather than having an awkward control scheme.
I like that this game came to you with your own personal journeys, it can definitely help create an emotional attachment, as well as just boost general motivation towards creating it.
I look forward to see where this game will go, if you decide to continue working on it :)
