I would enjoy it if:
Fun music, good visuals, boring gameplay. The idea of the game is very basic, and frankly the mouse based controls are just annoying. I'd prefer to move with wasd or arrows, but that would make the game even easier.
To improve:
Change main character to a bloodthirsty warrior
Change flowers to be the skulls of his enemies
Change music to Therion or something death metal 'ish'
Add gore upgrades
Add something to avoid...
Change door at the end to cute hottie with a dinner plate
