I popped the cartridge into my GameBoy, fiddled with the contrast, so I could make things out amidst the blurry scrolling the screen exhibited, and set off on my quest. With only two hit points and tons of enemies and traps to deal with, I was stuck in that first level for what seemed like ages. My character could float over dangerous spikes, but only for a second and a half. I worked hard to master the exact timing to start floating at the apex of my trajectory and to halt my landings right over a bed of spikes as I swooped down a mandatory pitfall.
That summer, stuck on a 32 hour car ride across the country, I found myself with nothing but time on my hands. I had just finished reading my new comics, ate my fill of snacks, and got bored of looking out the window anticipating our arrival. Having had my fill of Tetris and finising Super Mario Land multiple times, I had exhausted my tiny library of GameBoy games. Here I was, with not much else to do and so I found a scab to pick at.
Thanks to repetition and memorization, I had mastered the path through the maze-like area and was able to reach the battle with the daunting gatekeeper in mere minutes. Somehow, after butting my head against a brick wall for what seemed like ages (I was a kid), I finally managed to kick his fishy ass and open up the gates to the next level.
Best of all, I got a password that guaranteed I would never have to play that initial stage again, I had spent far too much time there to want to go back. I reached a new threshold and it seemed like the world had just opened up to me, offering different paths and places to visit. I was able to upgrade my character to fire more bullets, and float for much longer, letting me access brand new areas.
