Hey, thanks for playing! I have never heard of or played Diaries of a Spaceport Janitor, I looked at the trailer and I do see some similar things, I'll have to check it out sometime (If I can finish my library if that is.). Scrap value does fluctuate depending on the type, but it only fluctuates the total scrap value for each type, not each individual scrap has a different value. I don't know if I will keep working on this project as I will be participating in the Metroidvania Month Jam which is in like 10 days. I will try my best to add a few improvements before then, but after i'm done with the Metroidvania Month Jam it may be possible I continue to work on this project. Anyway, thanks for playing!
