That's great! I wish you the best of luck with your projects. Something worthy of note (you probably already know) - there are updated dev-builds available (download from here)... https://github.com/CG8516/DumpingGround/tree/main/EFPSE_DEVBUILDS
They have quite a lot more features than the original builds found on itch.io (the updates are explained in the text on the github page) but you MUST backup your project first = because if you open an old project with a new engine-version... the project gets patched to the newer version and there is no way to open it again in an older version (unless you restore then old engine and project from a zip/backup)!!
My advice is - finish the project you're working on first - then when you start a new project, try a new engine-build (I'm using the current bugtest5 version from 2 months ago, it has some great new scripting commands). To use a newer version - back up your old one (zip/7z the project folder) copy/paste the new_engine.exe in the project folder and run it - it will patch the project files.
You may find that really old projects wont run/function in newer versions (especially maps and scripts/states)- so it's probably best to start a new project from scratch. (I was forced to abandon my first project after years of work - despite having several backups of it).
I imagine the final build/version of EFPSE-CE will probably (possibly) be released later this year, so you could just wait for the final version to mitigate any potential future compatibility issues altogether.
