Just yesterday I posted in another thread that I should be seeking feedback more actively, so posts like yours are always appreciated, thanks.
When I read your post I thought you should become a Game Developer Psychologist: People show you their game, and you tell them what's wrong in their head. Just yesterday when I went to sleep (after it had become clear that this game will be less successful than my previous ones) I came to the conclusion that my heart wasn't in it and that's why the game is what it is. If decafpanda hadn't given me a lecture I would have spent even less time on finishing up, but as it turns out, it was not enough.
I was so excited about my next game that my thoughts and heart were already with that one before finishing Parasites United 2, probably even from the very beginning. The moment I uploaded the game I started the next project file in Stencyl.
From now on I'm going to look at my game ideas and ask myself which of these I would like to play the most, and then go ahead and make that game. Obviously I will still take into consideration how much work it will take to not repeat my mistakes from the beginning, but I'm getting better at Stencyl and my cost of living is still 200$ a month, so I should play that joker.
Since the next one will be a bigger project I want to make another change, and I know you can relate to that as a writer, is finishing the game, let it rest for a while and play it with fresh eyes. The first draft of anything is shit, as Hemingway said (I looked it up because I always suspected it to be a false quote, but turns out it's genuine). It will be freaking hard to restrain myself from publishing, but I'll remind myself how much better that will be for my career.
