I can't decide what to work on

So I started working a bit on helium boy. In my last post I said that I would still focus mostly on GMC though. However, shortly after I posted that I started working full time on Helium Boy and set up a schedule that I have followed pretty rigorously. I have made a couple of new levels and the game is nearly halfway done and it's set to be released in about a month and a half. I'm getting extremely tired of doing leveldesign though and this weekend I started on a new game... I really want to finnish a game soon so I can release something; but I kind of want to work on all three games at the same time
