Reaching the level 4 in 3 minutes is a lot of luck. What's best is to have a lot of fixed connectors placed next to each other. That way you can work backwards from them easier. If you get a level that doesn't have a lot of fixed pieces, just restart.
Very lame. Damage seems random, although the closer you get the less you do. If two or more enemies show up, it is impossible to hold them both back -- you WILL take damage. Lastly, when you are close to the enemy, i.e. inside them, you can't hurt them but they can hurt you? Lame.
The "boss" at the end is crap. I have no idea how to time it since the button comes up to hit whatever direction, but the guy just stands there like an ass.
Annoying game. Obstacles not only slow or stop you like you'd expect, but they actually *make you go the other way*. Yes, you BOUNCE off of giant boulders like a basketball. Not just boulders, but other dinosaurs and even sloped hills.
