First off, If you haven't played Goin Up by Florian Himsl (Komix) and Gonzossm you better do so now.
I've been addicted to this game since it came out. The gameplay is just too fun to put down. Gonzossm did a great job on his art work on his characters. Komix also has some superb programming skills.
I wish there was some sort of "cloud saving" built in to the game. There are times when I want to continue where I left off but at work or another computer.
Hope that happens :)
