I have to say, this is amazing! :)
Clearly it's in very early stages of prototyping and will need a lot of work, but the core mechanics seem very interesting and original.
Some suggestions if you don't mind:
- It would be great if you could just start typing an incantation at any time without having to focus the text field.
- Instead of the incantation text field being at the bottom where you have to take your eyes of the player and enemies, it might be better to have the input text appear right above the player.
- If you make a mistake when typing, it's time consuming to have to [backspace] a bunch of times to get to the typo. It would be great to have dedicated "Clear all" key binding, such as [esc].
- Instead of making simpler spells shorter, such as "mm", maybe make them typeable by just the left hand, focusing on the letters on the left side of the keyboard, so you don't have to take your right hand of the mouse. Instead of pressing [enter] to apply it, maybe press [ctrl] + [space], or just have it auto-apply when typed correctly.
In any case, I wish you a lot of luck and hope you continue working on it. :)
