I took a few years off making games when we had a kid and started a home remodel, but I'm working on making it a regular thing again.  I just recently finished UDLR after working on it for a couple months.  It was a really fun project to work on and try to optimize for accessibility (I particularly tried to focus on simplistic input and color blindness), which shaped a lot of the design and aesthetics.  

It started out as trying to make something that approached the idea of a maze with locks and keys a little differently.  Navigation is in straight lines, which makes it harder to go straight to an objective.  It presented quite a few interesting problems with trying to keep the player in bounds while still making it seem open and exploratory--the game is actually pretty linear (pun intended?).

The scope was also narrow enough that I was able to work on it on my days off and in the evenings after my day job.  By the end, I think I figured out a lot about time management and have a lot of reusable tools and code.  I'm hoping for my next project to be bigger and more complex.
