Oh this was very cool.
I really like the combination of puzzle game and RPG, the sliding felt smooth although as someone else mentioned it hangs in between moves a little too long to where it interrupts flow a little, still very fun regardless.
Also you tricked me, I thought this would be obtuse but it's very well designed with intuitive game play you can pick up immediately.
My one nitpick is I think it might lean too much on the easy side with how most the combinations lead to potions so I was never in danger of dying.
Nice work
