You're not too dumb, it IS vague like that. Even I didn't know the solutions and had to trial and error it 😅 In fact, I wrote down the solutions once I figured them out and put them on the game page so people could cheat if they want to. There really are lots of different ways to solve them.
For real, my brain had blanked at some point in development, like, "How did I just make a puzzle game, meticulously code it so that a solution is always possible, but I don't even know how to solve it!?"
