Added link to PC Demo in OP. After having more time to demo the game from my PC I can definitely say the game is worth buying. Now, I just hope it controls as beautiful on my Evo 3D as my pc this time. Also, I think I learned why skating up walls was problem, which was my major complaint. If you hold the jump button you can only go up a wall so far (sometimes barely) because you have a limited skate boost, but I found out its better in most cases not to hold jump to skate up a wall. Instead, jump on a wall and then press jump again to do a double jump and you will get a much high booster plus another in air holding boost to get you where you need to go.
As far as challenge goes I think its perfect for a mobile phone game not to hard not to easy. I know they wanted it to be balanced for casusal players but challenging enough for veteran not to be bored. I found a way to do just that. Yeah the game isn't to hard to get all the cogs and beat a stage, but to get all the cogs and energy balls is another story to get 100% on everything. Im going to ask the developers to add this feature to the game so veterans or hardcore gamers have an extra challenge. Plus the game has open Feint leaderboards for each level what's better than challenging other gamers high scores on a platformer.
Feels like a blend between Megaman and Mario for sure. Highly recommend if you're a platforming fan.
