I've added v1 to Newgrounds to play in the browser (requires the Unity plugin).
You can play it here: Newgrounds.com - Currently there is only 8 levels. Completing these shows a message asking for feedback, and I really DO want feedback! Feedback keeps me developing.
I like uploading games to Newgrounds to test it out with a trial audience, and get feedback. If I don't get good feedback, I know to ditch the project.
