Cool and beautiful game! The pixel art is gorgeous! Loved it, wish I could do something even close to that. The combat is a bit lacky but I guess that's intentional given then spell was the main focus. Feels like there is much potential to be made into a full game too! I also found the secret stash with all those sub-spells, which gives me a bit of a surprise.
The only issue I had was that sometimes the game lags a bit, and I felt a bit anxious when that happens, be it during platform and combat.
Overall nicely done!
