All great, except medal fail
I really admire the work you did within this 72 hours.
It's a full-fleshed boss fight, with great graphics and sound (apart from the fact that the weapon sound of the boss sometimes continues after I already respawned).
What somehow pisses me of and lead to a minus point is the medal fail here. It took me a fairly amount of time to finish the game and I did it within 2:40, even got on the highscore board; but I got neither the gold, nor the silver, nor the bronze, nor the Winrar medal.
Also I ask myself what's the exact reason for the high score buttons to be invisible (from technical POV)...of course that's not the best example of usability, but I personally can live with it.
