The strategy, as always for games like this, is to constantly circle around the edge of the arena while firing either in front of yourself or into the center. I was able to get a score of 5830 on my first run while using a trackpad.
"The Maze" level was awesome. Just as the game was starting to feel monotonous you threw a curveball. I'm only ~1/4 of the way through, hopefully you continue to surprise me :)
The first couple levels are alright, enjoyable even, but quickly, because of slow character movement, trial and error, and no mute button the game becomes tedious and annoying quickly. I appreciated the added bit of atmosphere thrown into the last few levels but it was too little too late as far as I'm concerned as by that time I only continued playing for the badge and not for my own enjoyment.
If anyone is curious, the room is an interpolation of the Van Gogh painting "The Bedroom At Arles" and his friend Paul is Paul Gauguin, another Post-Impressionist painter.
I get excited when I see a new JuicyBeast game. You guys never disappoint with your solid graphics and addicting gameplay. Knightmare Tower is no exception, you did a wonderful job on this one :)
