You steer a little arrow-shaped vehicle that speeds though an tunnel. Use the left and right arrow keys and steer clear from the cave's walls. Press the spacebar to resart your game and apply difficulty changes. As always feel free to remix this, I don't care if your change something, tough I'd love to see the game with improved GUI obstacles or something like that.
The game is a clone of the old arcade "Tunnel" game. For some reason, the only remain I could find on the internet was for the TI-84 plus - So here's a working version for PC. Every segment of the tunnel is just a clone of a single sprite. The tunnel or its segments are not actually moving, but they constantly are recieving the position of their previous clone (the one above them). You can think of it in a way as snake - There is only one segment that controls the rest that is only following its movements with different delay.
