Wow awesome.
I see no reason for this not getting a bigger audience! It's definitely a super time saver, I'm sure people will jump on board.
You just got yourself a new buyer my friend.
Your apps are awesome and I'm looking forward to the possibility to get bigger sprites, it's true that not everyone has great GPU but that's the point of having various graphical settings for a game, so i think it's truly worth it nowdays.
