I am uploading the updated Build with Level Select right now, go to my Archive.org page if you want to check it out!!!
Really damn awesome!!! Added your Quality of Life features to the specail Build. And some nice QoL features on my own as well...
Thinking about adding Bonus Levels to this Build, one example, it you do some extra Step you are getting Level 2 and 3 from your Sad Satan Revisited instead and than it loops back to Level 4 like nothing is different. So you can have Level 2 in different Filters and with Loadingscreen for Level 3 instead of being seamless like in my Build where Level 2 and 3 are combined to one single Level.
Just one example, If you add Levels like this the Pacing of the OHC Levels is not interupted. This is how I would add the DRSG and Clone Levels into this Game!!!
