Played it through to the end (of Village 1)! Was fun. Somehow I had such an excess of karma that I could have Strong Faries on 100% of the time, and I kept pressing Santa Boost as quickly as I could. It took me a while to understand how it worked, with the pushing the line of demons back, but was cool once I got it. I wish there were more buttons or options because once I had 1400+ karma I had the time to do more and was mostly waiting to press Santa Boost, but I'm sure in a bigger version of the game there could be something. I really like your hand-drawn artwork.
Also, not sure if you know but the graphics seem to glitch (at least on the web version). It seems after the first 30 seconds or so, I only see shadows of sprites and not the actual sprite images.
