Interesting idea I'm sure could be expanded on successfully! It didn't appear to abide by the 64x64 resolution at all though, sadly. A lot of sprites were smoothed, others were big, and the title was far clearer than 64x64 - which is odd, the thumbnail suggests otherwise, but in-game it's really smooth.
Thanks for your comments. I hope to keep working on the battle system. The game is indeed 64x64 ... I had just increased the display size in the index.html to 512x512 to make it easier to view/play. I have since updated it.
