Congrats Seth! It was a really great demo! Very inspiring and nice to see a "lifelong project" like yours suddenly become alive :)
You're very talented at everything you touch and you can really sense it well already in the 20min span of the demo. And the fact that you're doing everything alone definetly adds something more to the game. It feels genuine, honest, because the vision you had for it is not altered by someone else working with you. It's something very rare and you should feel proud to have accomplished this. It's very very easy to plunge into the atmosphere of NYKRA and it calls for wander and exploration. In a way the player is like Keu, naive and inocent and eager to discover the world around him, the identification works well. I relate already a lot to the very little we know about your universe I can't wait to discover it more.
The palette and the sprites are lovely and carefuly crafted you can really feel that you put a lot of efforts into it. The sound and music are amazing and really embodies the atmosphere and strengthens it. The maps are cleverely made and tickled my explorer side, and the small notes as rewards are worth it. The fact that almost everything is moving and animated is a very nice touch, it helps everything to feel more alive.
The only minor thing I wasn't really found of was the dialogue sounds, it feels a bit too robotic. Pyre from Supergiant Games uses the same kind of trick but does it in a different way, you should have a look at it!
Anyway, it's really promising and I hope it brings you motiviation to finish what could be a piece of art :)
Can't wait to see more!
