I put in an unhealthy amount of time into my entry, but I'm glad that I did in retrospect. I ended up really falling in love with my game's concept. I think it's basically my dream game. Or at least, it would be if I fleshed it out into a full-fledged game.
Also, it's pretty humbling to see what all everyone else ended up submitting. There's too much talent in the GB homebrew community. Makes it hard to compete lol.
