I probably should have had a tutorial on the buying part too just in case people can't figure out the RPG Maker UI (which isn't necessarily intuitive! Thanks for playing!
Honestly, RPG Maker is very... unique to modern games, or even the mainstream games 20-30 years ago, likely due to just going off the older versions of the engine in that way. Personally, I think everyone should have an optional quick guide on the unique aspects of RPG Maker itself, just in case it's anyone's first time with the engine.
