I had a lot of fun messing around with the different spells in this game and finding out what each combination can do. However, I found the movement to be a bit clunky as the character seemed to stop when you cast spells, and then you couldn't move for a while after.
I also had issues seeing the mana bar due to the dark blue on a grey background so at the beginning I was wondering why I wasn't able to cast spells because I wasn't able to see the bar. But changing the colour to a lighter blue should quickly fix that problem.
Gameplay-wise it seems a bit empty at the moment as there is a huge map but very few enemies. I think making the map a little smaller and increasing the enemies would have made this game more interesting as it just feels like a gentle stroll in the park at the moment.
I found that after a while, I started using only one spell combination. I understand the time scale of the development, but adding variation to the enemies would have been a good addition to encourage you to switch up the spells, such as certain spells being more/less effective on certain enemies.
Overall I enjoyed the game's ideas, and I would highly recommend adding a thumbnail/cover to your itch page as at the moment the game seems to be getting overlooked, which is a big shame.
