From what I can see, the visuals are well done. I like the pixel art, particularly the character portrait's texturing and shading. I also checked the audio samples you referenced, and they seem suited to the visuals. Unfortunately, since I don't see any way to play the game, I can't rate the game on fun or any higher for the sound or visuals since I can't properly experience them and confirm how skillfully they were implemented. Based on surface evaluation alone, though, I'd say you're off to a great start!
Edit: I posted this review before you uploaded the game. Will give it a quick playthrough and revise my review when I'm done.
