Thank you for your comments!
-Great idea i'll look into adding a toggle or a volume slider for it
-Anything regarding art unfortunately will take some time. This game is currently a solo project and my expertise is mainly in the development programming side. Though I do agree with you, and would like better animations down the line
-Currently you are allowed to swap between levels, but I am considering allowing you to instantly equip newly acquired spells.
-I am already working on a solution to highlight enemies behind objects. As for the UI, I agree as well. The game's UI is currently locked on 800x600 resolution regardless of the game's resolution. I am looking into changing this in the future. As for screen shake perhaps can look into a magnitude slider since I am looking to add more settings to the setting menu.
Thanks for the feedback I appreciate it!
