Cool concept! I think this could be really great, here are some loose thoughts:
- maybe add a direction on the monsters to see where they planning to move?
- It felt a little static to have to wait while abilities recovered and doing nothing, maybe add a action system where each ability takes some action but you can use a combination of them at the same time. More actions could be added while playing.
- It didn't feel like the keyboard buttons was necessary, It could work with a mouse, maybe add more interactions on the keyboard or a combination of mouse and keyboard.
