The concept is quite good but executed poorly.
I quite liked the look and feel of this game and the idea, whilst no means groundbreaking in originality, was quite fun. The game had a good style and I think that is something which is very important in games like this.
I liked the idea of the tricks and stunts but it is really poorly executed, you have the problem that there are areas where you need adrenaline to escape from - so I think to combat this you have made it possible to do tricks anywhere. However it doesn't really seem satisfactory. Doing a leg grab from the floor just doesn't feel right. Further in doing this you have made adrenaline pretty much useless as people can do tricks anywhere.
What I would suggest to counteract this problem is to make it so that you need a minimum jump/drop to do a trick which must be higher than what the player can naturally jump. Give the player a restart button and ensure that on each level/screen the player has enough adrenaline to be able to complete that level. (Perhaps if the player has less than 50 adrenaline at the start of the level/screen it gets upped automatically to 50).
I think this would really improve the whole adrenaline/tricks situation and make it a lot more tactical.
There are some other problems - a lot of collision problems. I'm sick of jumping through ropes when I should be grabbing them. The wall climb seems glitchy. You can do tricks on the grinding bars but because you don't land properly you can't fail the trick - allowing you to get to max adrenaline (not sure if this is a glitch).
If this game was better polished and perhaps a little better thought through in places I think it could be really good, but at the moment it's just not there.
