I was able to reach one ending where I started the ship before time ran out. It took me a few attempts to understand how to activate the ship, and I think the trial-and-error aspect was intentional. Once I figured it out, I was no longer confused.
However, if it weren't for the game's description, I probably would have given up because I found it frustrating to understand what I was supposed to do. I think part of the issue is that the ship has multiple levels and many sections look very similar. During my first attempts, I mostly ended up pressing random levers and hoping I was making progress.
Because of that, it felt more like succeeding through repeated retries and a bit of luck than through understanding how the ship actually worked. I didn't really feel like I was applying or developing any particular skill, and I think making the different areas more distinguishable or providing slightly clearer feedback could help.
Overall, the concept is nice. The goal of the game is easy to understand, it doesn't require any explanation, and it fits the theme of this game jam. Congratulations for doing this all by yourself, it is not easy to work alone!
