I invited over my friend who knows Unity and she helped me start out with my Blobby Volley remake. We worked for about 2h - me typing and her assisting me with stuff I didn't know how to do. In the end we managed to create a playable two-player prototype. I'm amazed at how easy it was and how much faster than with the other game engines I've worked with in the past (AndEngine and libGDX). Seriously, if you haven't tried Unity and are still using one of the low-level engines then make yourself a favor and give it a go.
You can download the current desktop version of the game here.
