Had a lot of fun with this! I don't necessarily think you need a lock-on function for your combat as Knight Shift suggested, but instead maybe some attack variation? The worm-looking enemies don't feel very threatening and I wish they responded to being attacked by becoming more aggressive. Finding where to go after obtaining the crystal confused me for a few minutes.
The saving/loading did work for me, so great job with that! Really love the comfy vibe in the town as well. Very fun, look forward to the next update!
