I can't give you the files directly, because they came from 2d platformer.
I asked mason repeatedly where he got the step and landing sounds from so I could go and download them from the source instead of using obs to capture them from the 2dp menu, but he only responded with, "The sounds come from various sources."
I can't imagine these sounds cost money, as 2dp was free, and still is.
If you still want the sounds, I guess I can give you the ogg files I have of the steps I captured from an older version of 2dp, but I didn't capture all steps because I didn't need them all.
Regarding multi-stage projects, I believe Remnant is the only one of it's kind.
I made this to show people what could be done with the stage builder if someone really put their mind to it, but so far no one has.
If you want to make a big stage like Remnant, be my guest, and let me know if you'd like me to test it out for you.
During Remnant's development, I had the honor of having Aaron baker and his mentor trajectory listed in the aac credits as Jordan verner; sorry if I misspelled your name; do the testing for me, even if I never asked them to do so.
A few people on this forum helped
out a little as well, though most of their posts are no longer present; as they were part of the older topics for this stage.
I also know most of the stage builder bugs, and please check out my manual included with your download of remnant, or on-line in the audiogames articals room for tips.
Hope I could help.
Later!
