My problem is that their premium content is only available via online saves at ArmorGames.com. Sorry, pals, no dice. Compile an .exe version of your game then we'll talk.

I don't like needing to create accounts for every game I want to play that happens to be partnered with different websites all vying for users, not to mention it sounds an awful lot like that premium content actually requires monetary support of the developers through Armor Games rather than just signing up for tracking purposes.
It's still fairly nice without the extra content though, despite the last few levels requiring some grinding (or foreknowledge of the 'correct' upgrade/talent build to get through the game easiest).
