Oh my god, I'm so happy to hear that!!! Yes, that's a known issue. The current implementation does literally not allow you to repair all objects, that's not intended 😅
I'm working on a fixed version with more content for after the jam ends :)
Hey! Thought I'd take the time to shoot you a message. You left a comment on my jam game back in december and since then I have spent a lot of time working on it and fleshing it out into an actual game. If you feel like it, give it a try. Would love to hear what you think :)
