Just from the demo, Dave is a fun and well made game overall, with some great visual design going on. The depth of the background shows a lived in world and has a nice parallax to boot. The funny little sounds/voice people make give a nice bit of character to the NPCs as well. I...admittedly had some issues with the dialogue but, that aside, it was a good time.
Good job, dev. I saw the game is on Steam and am definitely curious about it.
