One of the best bike games I've played
I'm not always a fan of these type of games, but I found this to be a great take on the concept. The photography feature was something I haven't seen before in a Flash game, gave it a kind of Tony Hawks feel, very cool.
Physics were pretty much dead one and made the gameplay feel smooth and intuitive. Felt great doing triple flips and such, too bad there was no point bonus for this, maybe something to expand on next time.
Graphics were great in parts, the menus all looked highly polished and the background was pretty nice. The levels themselves were a bit samey looking, could have used some environmental features like plants. Bike was alright, would look amazing if it was 3D though.
Music was fitting, liked the music player, felt like something right out of a console game. Few more SFX here and there wouldn't have gone amiss, like when you thud on the floor or walls. The recorded voiced were a nice touch.
I think you've done a great job of taking a somewhat overdone concept and making it feel fresh and new, whilst still quite a lot of room for improvements in a sequel. Great work!
