This was a fun bit, it was bold of you to try to flesh out a unique battle system in such a short time, I like the idea of the point system during battles, I think it's a cooler way to go about mana, if you make using guard worth while I think it be pretty good!
The story could feel a bit verbose in some moments, it could be a bit shorter in some places like in the beginning of the final encounter, or maybe just sliced a bit more through out the game, but the contents of the story itself were good, I was able to grasp what the characters were all about and what they were trying to achieve. ALSO cool there were two endings, went for them both.
Visually your game is super concise, I love the color pallette you went with, gives the game a sort of vintage storybook vibe, I dig it. The character portraits also looked super cool, especially the in battle ones holy. The soundtrack was also very solid overall, especially the one on the final encounter, very climatic.
The idea of going around knocking out enemies I think could work(it's a good way to make the player use the battle system), but I think you could introduce a exploration element to the mix, maybe instead of using the random encounter with steps you could actually walk around looking for enemies visible on the map.
Some technical things you might want to change is maybe change the doors to be on player touch instead of action button. Your implementation avoids accidental map changes, but it kinda confused me for a bit in the beginning cuz I wasn't understanding why I wasn't passing through a door. There is also a bug on the locked up animal person things, where if a random encounter triggers the game will just breakdown.
Overall, I liked this a lot, you did great!
