Nice and simple proper game, 2D, accelerate, brake, lean forwards an back. Analogue controls.
Level design is clever, inventive and interesting. Jammed full of really good ideas, like, really good ideas... you can ride a bike inside a giant metal ball, and over ontop of it.
Think the premise of ExciteBike... slightly over Americana'd and with too much content... the core game is very much totally fun and interesting... its suffering a bit from too enthusiastic level design and difficulty curve, i.e. the more straight forward levels sans mad physics are more controllably interesting as the more physics laden levels suffer a bit from, not random, but more tricky to understand as a consequence.
There are some very interesting problems that arise from having just the back wheel providing the power and you do find your self rocking the bike as you see on those mad indoor jump into concrete pipes onto tyres and so on.
Once you find the balance and the nuance to accelerate and not, its all pretty entertaining stuff.

Having played this all weekend, I can testify to it being fun, yet completely impossible on the 3rd out of the 4 difficulties in the more traditional single player mode.
I've just tried the tournaments, and they are just the tracks with a cumulative time, which is a nice remix... can't be that many people on it, on one of the tournaments I am 45th.
Admittedly I am trying to Gold each track before continuing to the next, I even spent 15mins on a track trying to gold it, until I realised it was a tutorial track, oops.
One of the more annoying traits, is that it doesn't obviously tell you what is required to get Gold until you've completed a track, then it'll just tell you what it requires to get the next medal, which may just be silver.
The general rule is no restarts (as there is a checkpoint system), and go... er.. quick.
User generated content doesn't really float my boat, but watching the vid are good for 5 mins:

Nothing will.
That 2nd one is all kinds of AMAZE!
Argh, this is really good!
... but user generated levels can only be shared with friends :s
It plays exactly like Kikstart II but... HD really. Very nice indeed, time running and the physics-y controls are extremely addictive. I'd say the price is a little high, which put me off, but it is definitely worth it.
Do Want! T_T
I'll definetly pick this up once work dies down, I loved Kickstart II.
Yay! I completed the extreme category this evening after much fiddling and bunny hopping! I did this with the lighter Phoenix bike whose steering is more sensitive than the Scorpion and shifting the weight of the bike is so much easier. I really enjoyed this, so much I neglected opensenses and Bayo!
hooooooolllllyyyyy sheeeeeeeet.
Really, its actually possible?
I like the bike recommendation, maybe thats why it was making me think it was impossible, the tought of using a different bike didn't even cross my mind. durrrr.
This game made me RAGE so hard - respect to those with the patience and focus to play it.

RedLynx doing a Trials HD lite Wii edition for the kids fun version thing....

Could be interesting, they seem to have an eye for 2d physics based games with wheels.
