100% worth the pricetag
A modern-day version of the NES classic Excitebike. This type of games have been very popular on Flash game sites since forever.
Really nice graphics for this type of game, the developers have done a marvelous job.
It is essentially a 2D game in a 3D world. You see your motocross bike from the side, basic controls to accelerate, decelerate and control your pitch (lean forwards/back).
The goal is to drive through the course as quickly as possible while avoiding obstacles and performing certain tasks. Each level have a set of objectives where you get tested such as; "Precise Aim" where you need to jump as close at a target as possible, "Highest Jump" where you jump as high as possible, etc.
Your records are uploaded and you can compare to other players online.
On the levels there's moneybags, if you collect these you can buy new parts for your motocross bike and costumes for your character.
There are 5 different "worlds" with ~8 levels on each, some levels seem to be reused or atleast portions of them are, but this is fine, they offer different challenges in the objectives instead.
Once you've started making your way through the main levels, a series of challenges start to unlock which are wildly different from the main game. I strongly encourage you to try the challenge levels
I think it could be a fun element if they added tricks to it, for bonus points. There are a few places where you need to do flips to get bonus points, however I would imagine something more freely. Perhaps that goes into a different genre of motocross games tho.
I can't really tell if the music is good or not, it's just ambiance. Full-focus on driving and trying to hit the jumps!
