Thanks for playing! I agree that I probably over-scoped a bit and ended up trying to add too much to the game (and of course I even had more ideas I wanted to implement too…)
Regarding the controls, I had trouble trying to decide how to simplify it, since the spell casting mechanism is somewhat unusual - maybe more mouse-driven control would be easier (like click, draw spell, click)? I wanted to make sure the player could always regain mouse control if they wanted, which is part of why it got kind of confusing. Perhaps more on-screen helpers (a real tutorial) would help instead of just a written description.
Glad you liked the presentation, thanks for your feedback!
