Use arrow keys to move, use space to use the sword. Press the G key to change the tunic color to green (skin color will be purple) and press the R key to change it to red (with blueish green skin). (If you press B it will change it back to blue. Since this game works differently than the original version the octorok respawns in the middle if it's stuck on a wall for too long, so watch out.
This is just a demo so far but I will make it into a game at one point. This is the next step in making a custom Zelda game. There are now two screens. I don't know how to make mass amounts of screens without having to type in code for every single one of them, but I'll try. UPDATE: I added an octorok to the top screen. If anybody notices any bugs please comment about them.
