Hy. Okay, i understand. :) Sadly these missing sounds will be a minus in the cartridge competition for your otherwise great game, i fear. But most important, that it will be finished and users can play it with everything included (sounds) then. I like these kinds of puzzlers, they make fun.
I don't expect an update to be counted in the competition anyway, I don't really mind though, this was about creating something new and getting more people to try it. It was really fun to explore the issues with designing a match 3 game with co-op and music / load screen will just be something to make the product feel finished :)
