Ok, lets see. The consept of "balance shape X in target" is not very original. Actually the only original things in this game are the ragdoll and the slow speed.
The slow speed is great, especially in levels that demand precision.
The only two levels that actually demand you to treat the object as a ragdoll instead of a box are levels 8 and 10, the rest are just like any in a "balance box" game.
Also about the simplicity, I like simple games and graphics, but this game takes that too far. This would be perfect for a school project for game engineering classes, but as a game it's too simple.
But I believe this would have potential.
Not bad, but I must ask that what makes this game different from all other "get that shape into that portal/hole in the end of the level as fast and with as few moves as possible by making it defy laws of physics and shoot itself (very innacurately) by dragging it with your mouse", other than the color theme that is.
This game is promotional to proper biking rules and wearing a helmet, which is a good thing. On the other hand, simply falling over without a helmet isn't a 100% shot at getting brain damage. And if you have a helmet and collide with a car coming towards you, you just won't walk away with just your bike ruined. Infact, you will be lucky to ever walk again, and lucky to live actually.
