There are quite a few glitches, yes. However, none of them make the game unplayable; rather, the most effort I've had to expend is to reload the page, and thanks to the nifty auto-save feature, I haven't really cared. I usually don't like economic games like this, but I've favorited this one and am giving it a 4 out of 5.
+1 because I love anything with RPG elements anywhere.
+1 because it reminds me of left 4 dead and I love that game.
+1 for addicting gameplay
Really, I didn't find anything wrong with this game. 5/5
The one thing I don't like is that once you get past around round 25, you can't just take a break and jump back in. I tried continueing a game from the day before aned got my ass kicked.
i think the only plausible badge would be a medium badge to obtain all three pure colors, all three breaths, and all three endings.
maybe a hard badge for endurance factor
