Once you've pressed the flag and read the text, press spacebar to start the game. Use arrow keys to move left and right. Press the 'up' arrow to fire. Press 's' to play music. If any glitch occurs, please refresh the page and it should work again. If it glitches and refreshing doesn't work, please look at the version's list. If it looks like this: Current Version - (undergoing maintenance) It means I am currently working on so it may not work. It should start working again in 10-20 mins. Thank you for your patience.
Also if you look below you'll see that I update it every so often, post in the comments anything you think would make it better and I will include it in a update. Version 1.0 (original) Version 1.1 (Added extra enemy: robot droids) Version 1.2 (rocket's faster; added an end) Version 1.3 (updated scoring system) Version 1.4 (sound when firing) Version 1.5 (shoot with 'up' arrow instead of space; slightly less delay when shooting) Version 1.6 (created a sound option; robot droids artwork updated)
