I had a lot of fun playing the game! I found the tf descriptions to be very satisfying and I enjoyed having them active always. I felt the same for almost every boss! The way to defeat them isn't super obvious so there's multiple ways to defeat them either by human/normal rpg strategy, or using the advantages that monster form gives. Also I loved the mechanic of 'infecting' human characters to give them monster buffs, really creative!
I also liked the variety of tfs in this game, from humanoid monsters and ferals and even some inanimate which I love in rpgs.
Also spoilers for the final boss for whoever hasn't played it yet:
Personally, the final boss is the weakest part of the experience, mostly because it forces you to *only* use the champion heroes to defeat the *first half*. This goes against what I enjoyed on the other boses and, after defeating the first phase, there's nothing that tells the player that humans are resistant to petrification, which led me to throw a bunch of humans-turned-champions into the final boss, leading me to a bad end and forcing me to replay the entire boss again, and, with the help of the playthrough get the real endings. I understand it conceptually since the Warlock is the one who created the curses in the first place, but I'd say that I was a little disappointed that there wasn't a special charm that allowed you to be inmune to his curse, at least for one transformed character.
Once said that, I found the endings really amusing and ironic, very fitting to the idea of the game!
Overall I really enjoyed this game, the tfs, the endings, and the battles. I don't want the feedback I have to make you think otherwise. Your games are some of the best tf games out there and I'll look forward to supporting you to make more in the future :3
