Really fascinating to see RPG Paper Maker used this way. Just played through the game and I thoroughly enjoyed it! For some reason, however, I had problems executing the spells. I was only able to cast a spell once or twice, and I had to hold the Left Alt key for at least two or three seconds before anything would happen. Not sure whether it was intentional, but at the end, I kept on getting teleported to the first level when I touched a certain wall.
