I'm honestly surprised by the amount of content this demo has. The 'card matching' gameplay for battles is pretty fun, and I'm very happy with the amount of NPCs in the game. I'm grateful that there's a detailed tutorial on just about everything the player may be confused about; although, I admit I skipped it as there was a whole lot of it.
There's definitely a lot of potential here from what I can see. The demo ran smoothly despite it lagging on OBS, the graphics are nice, and the music was alright so far. I do hope there will be more BGMs though. The most interesting part to me is the plot and the history of the world so I hope that'll be a bit of a focus at some point in the future.
Overall, this is a gem with a tremendous amount of potential so great job!
Best of luck with game development~
