I told this many times already and I will say it again - just take all the time you need, Komisari. It is realy rare these days to find a game of a high quality with realy good story. Yes, Im saying this directly, your "adult game" is of a much higher quality than 80 percent of "serious" game trash that, as example, can be found in android google market. Just take your time and, most important, take care of your health. I have a problem with my eyes too (unfortunatly permanent, with a possibility that in around 15-20 years... or sooner... I will become completely blind) and can say for sure - eyes are the most important part of your body.
Remember, you are the best and community will wait as much time as will be needed. No need to make posts with revealing of work progress. We just want to know that you are alive, you health is great and you continue to develope the game. No need to give any proves, just "Im fine, filling well and Im working" will be more than enough :)
