5/5. I don't see why people are saying that the premium content leaves a greedy impression, I mean, you're getting an awesome game for free, and this guy has spent alot of time on it. He deserves something for it, and hey, if you don't want to pay, that's fine too, just don't complain.
@epic_win_46 Tukkun himself told Greg after playing the game not to give it badges because it makes adding updates a pain in the ass, which any long time player should know.
The only problem I see is that later in the game when there is alot of weapons to chose from, the 8 squares in the shop aren't enough to get what you want even after leaving combat 3 or more times.
