Click the green flag to start the game. Left and Right arrow keys turn your ship. Up arrow key propels your ship forward. Space bar shoots. You can switch between a higher-damage basic shot or a less accurate rapid shot by pressing the 1 and 2 keys. Defeating enemies gives you score and changes the number displayed at the top. If you get touched by the aliens, you lose a life. Get touched three times and you lose.
Thanks to Warfame with code templates and video help with some issues I've had previously trying to make games like this. The lag is uncontrollable :( I made this game initially for a game unit in an english class, but I kind of thought of it to be my own (and a friend's too, thanks Mike for helping out). I wanted to make something galaga-esque but I wasn't good enough to just do it on my own, so I searched a tutorial on youtube to help me out. Visuals are all me, enemy spawn is me, movement is me, but I used the more complicated codes from the tutorial to help. Credit to the one who made it is above. I've received reports from this game that it lags when you use the rapid-fire, so I did my best to change some of the values without taking away from the gun. It might still lag.
