Hey! Thank you again for your very insightful review. Today, I finally had the time to play your game, and there is a lot to say:
Your take on the theme is definitely the most unique and creative in the entire jam, period. Also I'm a huge fan of turn-based games, and yours is really unique. I definitely encourage you to continue developing this game. The idea is great, and I see a potential GOTY here if you manage to polish it.
Talking about the strategy, it's super well thought out. You can swap parts that the enemy has already destroyed. It sounds broken, but if you don't have a strategy, you will end up losing anyway. My strategy was to go stealing the tail first since it's the only body part the enemy has and I don't. Then I exchanged my destroyed left arm with his, then used my demon arm to destroy his remaining arm. In this way, he will have a difficult time destroying my head since he just have legs to attack. Once the arm is destroyed, I proceed to destroy the demon's head, and... it didn't die? Ahhhhhh HAHA. That would had be very satisfying if worked out
AThe art and fonts used give super nice dark fantasy vibes! Love it. Maybe it would be nice to add some kind of visual cue to know wich body arts are destroyed, so i dont need to check body part one by one to plan and strategice.
Regarding to your music curation for the game... Let me give you some advice as a composer (And gamer). The title music is long, beautiful, and elaborated; the boss battle music is great and super repetitive and catchy. However, It would work better the other way around. Strategic, challenging boss battles like yours are long and invite replayability. In that case, using very repetitive music is an awfully wrong move, even if the music is dope (The track you chose reminds me a little bit of the Mother series), the high exposure to repetitions will make it annoying over time.
So summarizing the advice, for long levels or bosses, difficult or replayable: Long-format music will be a good choice. In the same vein, the shorter the scene, level, or the easier and less replayable it is, shorter-format music will suit better
I enjoyed the game; your idea is nice, and I will give you the highest score I have given in this jam. Very well done. If you continue developing this idea and need a hand in any audio endeavor, feel free to send a message; I would be glad to help :D
Wishing you the best in this jam
