This is a fun idea, and I really like the stormy vibe! I agree that it would be nice to remove the junk once it has been placed, but I could also see how that could be exploited to climb forever with just one or two pieces, so you'd have to be careful! Also I did manage to get stuck in the wall at one point and couldn't continue. It might be nice to have checkpoints at each stop that you could revert to, just in case that happens. Other than that, really good job, I enjoyed it!

This is actually pretty neat but its very easy to make a mistake that makes it very hard/impossible to use the stairs youve been making, being able to remove the junk after putting it on the building would be helpful

Very sorry, but I did not get how it worked
