Thanks for playing and the feedback! I'm happy you enjoyed the combat as I've been concerned that people don't really get it.
You missed the boss portal! (the red one in the room you spawn in). The idea is that you prepare as much as you want before the boss fight, and when you beat the boss you beat the game. I might have to clarify that in the game though.
As for the future of the project I'm not entirely sure. I've honestly thought a lot recently about doing an off-shoot from this project that's more focused on just controlling one character but I haven't made up my mind yet. If I keep working on this I think I have to find more ways to justify the fact that you control two characters and make each character more unique. I already have that if you throw a fire spell into the spin attack a fire tornado will be created, or if you cast an ice attack into the spin attack the enemy will get frozen. More stuff like that. Also maybe more defensive/utility stuff as well. Perhaps you can lift and throw heavy objects as the warrior, or the Witch has a teleport as her dash, which has a longer range but longer cd, so you might tag to her just to dodge a big attack.
