This is brilliant
I actually unironically look forward to dying with this addon enabled, and find entertainment watching my previous attempts play out and seeing the silly ways they die or the unintentional feats I did in the past unfold in a different perspective
The only things I can really suggest is making the addon save your settings for it (Tiresome having to disable the things I don't want every time I use it)
And perhaps make the player's ghosts transparent. Having a lot of them around can make it a little hard to see past'em.
Also, this DOESN'T require a lot of RAM. I play SRB2 on a toaster of a laptop, and the mod's given me zero problems with performance, even when I had like 32 ghosts in a level.
Edit: Oh yeah. When reliving an iteration, if the iteration happens to switch to firstperson, the camera breaks and just remains where the iteration stood at the point of switching perspective
Also, the RAM thing was because the script has to store the individual data for each frame of each iteration, and I thought that would quickly become a huge amount of data to store. Thanks for clarifying!
