Hiya Princess no worries it's a lot to get used to. My understanding of Ren'py, the engine that we are building Psychic Connections in, does maintain a consistent save-state memory. Provided we don't release an update that outright breaks a save and requires you to restart. (Which unfortunately, will no doubt happen at some point in the future.) You should be able to keep your saved progress.
Additionally you can get the next build by simply re-downloading the game off of our itch page which will be updated with the latest version of the game on the last Saturday of every month! If you're following us on itch (which I already know you are) you should also get a notification whenever we post an update or devlog.
