Great game, but overall a huge time waster. Battles have a small chance to freeze, games cannot be loaded if you refresh the page, you gotta restart.
However, you keep your rare totems upon new game. It's nice and all, but with a random generator that has left me at roughly 30% of an actual 50/50 rate on paper after four hours of gameplay, it definitely feels like something is off. Was going to give a somewhat lower rating for this fact (because I remember the exact same thing happening when this game first came out, spent about eight hours on it then), but there was a lot of effort and creativity put into this game, so I say at least 4/5. All the game needs for a perfect score is some minor tweaking.
