I like it. Mediocre gameplay but really interesting and funny story. I got over 10,000 points, but now I keep dying at the "hang in there Thundernut" line. I keep getting pierced by arrows, and I'm not sure if it's even possible to avoid enough of them. They appear to be randomly generated, as far as I can tell, so maybe it's only possible on a certain percentage of playthroughs. I'm not going to keep trying because it takes several minutes to get to that point.
For the people who are experiencing lag, try using a different browser. It lagged for me in Google Chrome but worked fine in Internet Explorer.
