I understand. You are right. If Gates of Hell would release today, that would have been a better reception I think. Isolated will be much better at release date. I'm sure of that.
As for Gates of Hell, over time, remaning bugs will be fixed when it can be, I'm sure of that. And if Isolated is a success at release, it may offer then a new window of interest for people revisiting SymplGames/Gaia Publication. :-)
For Isolated, I was impressed by the tutorial improvements of the last spring 2023 build. I remember to have said a lot of emphasis on that and you did it a great way!
