I like the style of this webpage. The font, the colors.
But, about the game..
Seeing how the player character always died in the video I have to say this is an incorrect game. The enemy (usually bats) comes fast from down of the screen, flying before of the graphics and it appears really near to the which. You can't avoid an attack like that. First time it happens at 1:22 in the video. How did they get there? They can fly in front of the ground graphics but the which can't fly there. This is an incorrect way to make harder the game. Even without this it is already hard enough.
