Use arrow keys to move left and right. You can move up and down a little bit too. Look out for the trees! Try to touch the finish the gate.
I've only made a few tweaks, nothing major. The trees move towards to top of the screen. Once they've reached the top, a new clone of a tree is created at a random location near the bottom of the screen. Horace now moves in the direction he's facing (but just a little) even if you aren't pressing any of the keys. An idea for modifying the game further would be to change the left and right controls so they only change Horace's direction, and to leave the x coordinate changes to rest of the code. I used to love playing this game on my spectrum.
