Very cool entry! I made it safely to the top! Like usual for RPG maker the combat and movement are pretty great. I liked the story and concept of being able to take over different enemies and spend points on skill trees. I liked the art, even if you used some base assets and there was a bit of inconsistency there. The final boss having extra mechanics was great and I wasn't expecting much more than a fight, so good job changing it up there.
There didn't seem to be much incentive to change characters, by the time I got into the cave (the first time) and leveled up, I would really have to make a purposeful effort to die to take over another body. Although at the end I wasn't paying attention to my health and died to a pirate but was thankfully able to level up on some of the chickens you put around there and still beat the boss.
I did somehow manage to have the first cave fill up full of monsters and I chose to restart instead of trying to fight through them. So tuning down the spawning or having fixed enemies would resolve this. I could do without the long ramps that don't have much going on with them, either shorten or add something fun to do. The dark dungeon too didn't have enough landmarks to make it easy to navigate. You'll see in my video I'm literally saying "alright I'm going to end it here" as I happen to turn the corner to the exit. I had this issue with another rpg maker entry and the darkness just doesn't work well from a player perspective without significant landmarks or a minimap (which may defeat the purpose entirely), or it could just be me. Lastly, at the beginning I accidentally went back to the sea lady goddess instead of saying no so when I fought the pirate as a level 1 pirate, I had to die and switch back to the chicken to get my spirit up fast enough to take it over again. Not really a soft lock, but an unintended consequence of going back to the safe area without leveling.
Fun submission. Gameplay here
