I could totally see this being a really cool game where you have to route a path for people to follow! I think to improve it you could have made it clearer when the node is connected to a ruin (like some particle explosions or something) and then made it replayable with perhaps random terrain and adding multiple paths and being graded on their quality (however you would do that (maybe proximity to scenic location / nodes used)) I do understand that wouldnt be possible in the short time allotted but you should totally do a post jam version!

These are all really good ideas that I definitely want to add on top of continuing to develop on this idea and hopefully transform it into more of a FPV mountain climbing and mapping sim with a bit more challenge and excitement. I think I'll procedurally generate the landscapes, work on the ruin logic and effects, add some more complex mechanics and work on some sort of route grading by safety and scenicness!
