Played through 0.9.5.1
First off, glad to see this got updated again, even with such a big gap. I hope to see this game completed soon.
The path to the two princesses feels a little redundant with 2 panels on each path just to get to the next spot and nothing but moving between teleportation circles. I also couldn't notice the door that opened up in the floor the first time, but eventually found it. Perhaps the hole tile could be replaced with something else to be a little more visible.
Another thing to mention is that the one-use keys for these sections make you worry about whether you can get everything that's in the area. I'm sure there's enough keys total, I just don't like the idea of possibly being locked out of gear/rewards because I misused one or two keys.
Was a little confused with the secret story mentioned. The instructions make it a little difficult to understand how to get to it. So as far as I can tell, I haven't seen that extra bit of story. This could also just be an error in translation, which is understandable.
Still, solid update. Did not have any issues using an old save, although I'm sure I'll copy one over again because of an event in this update to see what the results are.
