Just watching the youtube clip looks like the game is fun. Is it possible to play with controller?
Maybe L1 and R1 could switch who im healing, while X, Y, Square, Circle is the spells i cast, in addition i could maybe hold down L1 or R2 and get another set of 4 spells.
As someone who mainly played healer in World of Warcraft for many years, i do want more healer focused games.
One thing i saw in the video was that it was hard for me to know who your party members was. After a while i understood. Could maybe have their names in green text below them and health bar above them in addition to their health bars down below the screen.
