I agree with the other comments that this is a very faithful homage to Tokaido. Well done!
Overall presentation is very professional. The art and music/sfx really help you feel immersed in the world.
I do wish there was more explanation in-game or more graphical indications when food was eaten or damage dealt. I also didn't quite understand the symbols that rolled(?) when the hounds respawned. I assume it was stats related, but I wasn't able to figure out what the symbols represented. I also wasn't sure what the status on the upper right indicated.
I was able to win (on Easy) and I think I learned enough that I could probably go back and win on Medium too. (I saved to one of my collections to check back in case you make any updates).
Overall very fun and enjoyable!
