+1 Hat!
I love this game, it's repetitive, but still manages to make me want to play it over and over. I only have two small problems with this.
The first is that whenever you spin a game speed increase, the entire screen whites out for a second. It doesn't last very long, but farther along into the game it can really mess you up.
The second is with the reverse treadmills. I find that sometimes, even if the wind is blowing one way, you'll still be pulled in the opposite direction (Where the wind should be coming from/where the treadmills used to be pushing you) for a couple of seconds. When you have three things pulling at you when there should only be two, it can make it extremely difficult to figure out what you should be doing.
I haven't had any problem with the medals, I'm not sure if that's because you fixed it, or it might just depend on the person.
I'm also curious as to if it is possible to land on the 'win the game' tab in the wheel of awesome, because I think that would a medal you could add. I actually think that there could be a lot more medals you could add that would go beyond scoring really high, so people would have motivation to continue playing this game even after they earned all the score medals. Things like a '+5 Hat' medal, or a '+10 Party medal' would add more variety to the medals.
I think this game has potential for sequels. Not necessarily more T-Rex on a treadmill games, but games similar to this that involve a T-Rex, and a Wheel of Awesome. Or maybe a Wheel of Doom, or something of the likes.
All in all I find this an extremely fun game. If you just fix the few glitches you currently have, this game will be a 10 in my opinion.
