I really liked the different dungeons so far, and I'm looking forward to more. I really liked how the bosses sometimes made use of special attacks when the status on a character has progressed enough. On that matter, it would be really nice if the boss in the horse-chapter would get some additional drawings when they are riding one of the characters but I would also understand if that is too much work.
On the topics of bugs etc: The horse boss seems to sometimes get caught in a loop where they will only use the "Good horse"/"Bad horse" attack which does no damage so they will eventually go down without a problem. I'm also not sure what the "Good horse"/"Bad horse" attack even does and what triggers which, and my grace seems to also go up at random times during the battle. Maybe that was explained somewhere but I got quite confused on that. The mummy boss seems to be almost unbeatable when your party is fully mummified, even with one character wearing the gear that negates mummification and max level, he outdamages my team quite easily. I'm not sure but I think a fully mummified party is basically softlocked against that boss.
In any case, I look forward to more :D I hope you have other fun scenarios planned, I'm personally a big fan of bondage and straight up transformations, I wonder if I will be lucky with what you have planned for the future ^^
