First of all, know that I greatly appreciated your game, as simple as it was and despite the few things you overlooked (such as the possibility to open the menu while resting at the INN, or the NPC's sprite not disappearing when fast-forwarding through the dialogues).
I finished my first playthrough at 100% completion in 133 minutes, and I gotta say, it was worth every single one of it.
Now, on to the pros and cons. (Contains some spoilers for the game, only read if you've completed it or don't mind being spoiled minor details.)
-Many team builds and decent number of classes available.
-Intuitive gameplay with obvious weaknesses/resistances for the foes.
-No real difficulty spike, said difficulty matches the recommended level required to clear the dungeon.
-Very useful spells. (Gotta love Knight & Dancer )
-The fact spirits curse you with debuffs at Turn 1 really spices up the challenge, I simply love it.
-Even if intended and if I respect that, the game is short.
-Enemies don't tend to vary that much between dungeons. (Fighting the Spirit of Light twice in the same dungeon, why not.)
-Okay, that's not really a cons because I have to fill this section somehow, but Recover All makes it too easy even with Healings/2. ^^
In conclusion, your game is purely and simply good in its own way. I highly encourage you to keep going.
