Wow, this was absolutely fantastic! I had no idea it would be this addictive! It's a pity I can't get any better at it. I mean, my number of kills doesn't go up! It's hard, but still wonderful. I love the variety of enemies.
I wasn't even sure what the crystals did at first. I then realized they were used to level up. With such a large screen, I can't take everything into account! I hope this stays up for a long time. My favorite powerups were probably the killer rabbits. Yes, of course I love "Monty Python And The Holy Grail".
