Project Seaborn is an action RPG with a unique battle system that I was developing in Unity. I put its development on hold to work on MythoMania.
The battle system has two phases, the planning phase and the battle phase. During the planning phase, you perform turn based actions in order gain an advantage. In the battle phase, you enter into bullet hell combat where you can make use of your selected party member's unique weapons and skills.
You can see how it developed through my devlog series.
