Ah I understand. Well I hope that you will be able to pick it back up soon. I like what you are doing with the Sushi Quest brand/universe that you are building. It's very... "Naughty Dog" of you.

One thing I did notice though and I think it might help with all of your games appeal. The colors in your games, though nice, lack a certain "pop" and I was looking at it recently and I noticed that most of all your colors are pastels and/or slightly de-saturated of color schemes. This gives you graphics and assets that will all match and blend well together, but aren't as exciting as they could be. A deep color scheme is one of those things that will attract the player's eye. Your graphics are very nice to look at and have a cute polished quality, but lack a specific burst of coloring that will add excitement and energy I think. Especially for something like a racing game where things are going by rather fast for the player and you expect the game as a whole experience to be very exciting in every aspect.

This could be something that you could try add interest to your game (as a patch/update) or a sequel to give it some brighter colors here and there to try and catch the player's eye more. It may seem like a silly thing, but I'm quite sure this is something that would keep potential players coming back to see your game videos and demos with eventual increase in purchases in the App Store.
