I like the graphics, the outdoor locations, the characters, and the story concept. The music is nice too.
I didn't really enjoy the battles. They felt very repetitious. As far as I played, the strategy is simple and never changes (choose to heal if health is low enough to die from a critical hit, otherwise choose to attack). Missing in battle felt like it was adding time without adding any strategic complexity--I just do the same strategy again after missing. I probably wouldn't mind the easy, unchanging strategy that much if there were fewer battles, but the encounter rate seemed very high--often I'd get two or three in a row without being able to move, then manage take only one step before getting in another battle. As much as I like the art for the cat, rat, and bat, I think maybe having 10%-25% of the current encounter rate would be a major improvement in the experience. (Adding a bit more decoration to the rooms (or just having fewer rooms to go through) would also help a bit, I think--going through a bunch of empty rooms kinda makes things worse.)
I also encountered a couple bugs while playing: After I picked up the Saltpeter, then got in a battle, the Saltpeter reappeared. I didn't go back to pick it up again, because I didn't want to fight another 2-3 battles before exiting the room. After I went back to the witch, she said the "thank you" dialog, then the "missing ingredient" dialog again. I tried talking to her again, and she just repeated both dialogs again.
Ultimately I stopped playing because I didn't want to spend more time on the battles. I still kinda want to help the characters, and I'm curious to see what their objects and resolutions are, but the idea of going through several dozen more battles to do that is rough.
