Right?! I like your sprites btw. They're taller than the default chibi!
Yes, I also used the default assets as references for color palette and shading. It saves me time. ^-^
Thanks. I also based my enemy ideas from the default graphics (like the plants and spiders) but I do have some original enemies like a soldier from an empire, a spider-human hybrid (humans who have spider traits a la Marvel's Spider-Man), and elemental enemies.
I was looking on the RPG Maker Forum and found a Book Menu plugin from taaspider. I don't know if Lawmage Academy could use it but I found it could be used as a codex or help menu though the main menu may need some editing. Also I have tried out the demo specifically version 0.6 from November 2020.
