How would you make this game interesting?

I came back to check out this game after like ages and I lowkey see the potential (Really slow moving potential) for actual gameplay, and I was just thinking if it did what do you guys think it should change or add to make it an actual playable game. Like the aura's would be cool to have as combat but the lag would be insane and that like effect on the floor would make it way worse. It has bosses but they're subpar at best so what ideas do you guys have
