This was just so nice, through and through.
There's fun text packed into every inch of this game. Every map is lovingly crafted, dense with decoration and personality. Character portraits, animations, and sound effects are used to incredible effect. There's more unique creative voice in here than I thought was possible with RPG Maker. The "normal life, except fantasy" setting is a joy. And of course, all the Facets (and even Wayward) references made me very happy! Everything about this game made me want to keep playing to see what silly, fun, and/or cute thing would happen next.
(*person who just finished playing Ys VI voice*): The difficulty gave me an Ys vibe. ...both in that levelling up once or twice made a huge difference, and in that exploring could yield extremely cool items. To answer your in-game representation: no you definitely did not make it too hard! The variety of healing options and the high escape rate made it all feel quite generous.
I enjoyed the texture of the battles, too. Boss fights had me using pretty much every battle command, keeping it fresh throughout. While I didn't really ever use any of the low rank spells, I liked having a variety of options. Daisy was a lot more effective with melee attacks than I expected! I really liked how using certain Specials on certain enemies triggered special dialogue. Makes me wonder what other things like that I may have missed...
This game just rules. I aspire to make an RM game that gets its hooks into folks as much as Daisy Goes to Slime Castle for Tea does. What a delight. I can't wait to see what else you make!!
