Been excited to play this one since you first brought it up in the Discord. Haven't finished yet but here's what I have so far.
Gameplay: I liked the fast leader switching and the way it affects dialogue was a great little touch. It did come at the cost of not being able to run using the keyboard (as far as I'm aware). I also would've liked it to pause the game if possible so monsters couldn't attack you while you switched. The shadow footprints were welcome as well, albeit navigating the main town outside of them could get confusing especially when collecting the three shadow essences. I would have liked something like a quest log where you can see where you're supposed to go.
Combat: Action-based combat was fun, although I wish there were more of an indicator like a flash when you hit an enemy. Likewise, I wish when enemies hit you, you could see how much HP you lost in that moment.
Comedy: Hard not to love how quippy the cast is on a regular basis.
Sound: Your buddy writes some damn good music! Quality of the music was great all around although some tracks didn't fit their surroundings. A weapons shop theme has no right going that hard. Ambient SFX added a lot to the game as well.
Visuals: Pretty standard RTP fare done well. Loved the ambient weather and time of day effects.
Story: Nice to see a more typical RPG-style story. While I liked the overall writing, the story felt kinda disjointed from time to time. Could have used a spell check as well honestly.
Overall very ambitious and refreshing.
