What started as an exercise to recreate the multilayered terrain system of Warcraft 3 ended up being a prototype for a top down action RPG. It also features a pretty deep combo system (hence the name), dual wielding, projectiles and a creature system that allowed me to quickly add enemy types with their own behaviors and equipment.
This project had to stop mostly due to technical limits. I had trouble to properly manage a large number of objects and actors in Unity at the time. If the game can't run smoothly when so little is implemented, I usually consider that as a red flag for a long-term project.
I definitely need to reuse the terrain and the combo system in some future project. Holding two spears at the same time to get special combos never gets old.
