Galaxian

Interesting easter egg, the game takes place in space, and if you furiously mash the space bar, it'll scroll down the page! I love these 4th wall breaking secrets. 5/5!

Nice game! beat all the levels and my only real complaints are the ship controls (If the ship meets your cursor, it'll suddenly decide to go into the exact opposite direction until you decide to move your mouse or it's ramming into a side wall.) and the loud noise whenever you pick up a "power up" (do these powerups actually do anything? It seemingly made no difference in gameplay but i could be wrong) and when you select a level. Otherwise, the game looks and plays pretty well :D
