Hi, thanks a lot for your comment! It's great to know that you enjoyed it. I will continue uploading episodes to YouTube (normally 1 or 2 each week) and from time to time I guess I will update the demo also with new episodes. I hope to be able to finish at least the main story (without choices) this year.
I thought about voice acting and maybe I could do some crowdfunding for that (??). I read that voice acting costs quite a lot. But I was also planning to keep this a free game, at least for the version without choices, so I am not sure about it. First now I want to complete graphics and story.
Regarding image size. I made an earlier version with Tyranobuilder and there they suggested 960x640 because it's easier for mobile phones. That's basically the reason I got stuck with this. Larger image size also means longer render times.
