General thoughts from my playthrough (I played on Normal):
- Overall, this game looks NICE. I love the inclusion of Tonbi's tall sprites and Low's battlers. There's even a custom Harold sprite. FSM for maps is always a good choice. Even the window skin and font have style. And there are custom-drawn busts for the character speaking parts too.
- There are some minor spelling errors here and there, but nothing that makes it unreadable.
- Battles have at least enough balance that they don't boil down to "just spam attack," but they mostly do boil down to "use your strongest spells"
- I like that leveling up means you fully heal. Keeps the game moving.
- While the battles are fine, I'm not feeling like they were very necessary. The battle system feels disconnected from the rest of the game, aside from the battle with Reid.
In summary, the game overall looks great, and the length is perfect. It's a good game jam game.
