You can change the controls in the options menu, the default is definitely not advised.
Resolution in RPG Maker is a difficult thing as it will always zoom out everything, make it too high and you'll have tiny text in massive text boxes and your characters will be very small in a map that feels far too big for them (Alternatively if the map is too small, you can tell the map wasn't made with the view in mind)
You are correct that everything was made with royalty free assets from RPG Maker (VX and MV) or other content creators who allow their material to be used for free if credited.
With all that said, we're sorry you feel the product was lackluster and hope to do better in future titles.
