In regards to the author comments, no it's not that obvious. More importantly, this game has no sense accomplishment or fear. The screen just reloading doesn't make me feel defeated. A simple "you lose", or "Ha! You lose BOI!" would help. Some music, sound effects. Things of that nature. The graphics are simplistic. It looks more like you've developed an engine than a game.
I'm pretty sure if you dressed this up with music, sound effects, a points/score system, a preloader, menu, credits, lose screen, win screen, and some levels, this'd be a fine game.
