.NET Runner - Visual Basic Game

What's up ! Here's the second game I made, called ".NET Runner".
This is based on the famous Iphone/Android game "Line Runner". I spent a while creating the gravity, and finding a way to make the player moving, without doing a side-scroll. Actually, it's all the elements that moves, and not the contrary. This give you the illusion that you're walking. The goal is simple, you need to jump to avoids all cubes. To make the game harder, I added the ability to move back and forth. If you simply jump, you'll fail after 3 seconds. Even if it looks simple, I assure you it's really hard.
