All guard graphics are now complete and I've even added a new guard. This means that I just need to finish a couple new coding tweaks, about half of the object sprits, most of the boss graphics, all the sounds, some of the music and most of the maps. I know it sounds like a lot, but hopefully with the guard graphics out of the way, progress will pick up the pace a bit.
I'm not going to make any promises about a timeframe since it will inevitably not be met.
