Did not finish, since I'm hoping to get some other game ratings in before the deadline later today, so bear in mind this is from someone who stopped at the start of Section 2.
You two are wizards. What the hell. I knew from the very start of the jam that this was going to be the winner from what everyone else was saying about it, and it has been completely worth the hype so far. I'm sad I have to put it down since I'm pretty sure I know where at least one thing is headed and it's going to hit close enough to home to hurt. (I mean that well.) It looks fantastic, it's gotten a few laughs (oh my god the seagull,) for a game jam it's completely transcendent. I'd have my doubts on whether or not this could even be done in an 8-day timespan but, no, the theme is very much interpreted in the way you've stated here! It can't exist without B-Jam!
My only real gripe (besides that tbh it does seem like it's a bit long for a jam, but I think the voting period should've been longer anyway) is very early on, with Agatha's shop. That sign lies to you. Only GreenTea and Ale are at their listed prices, and of those, Ale lies to you about its effect. It heals one party member for 4 HP. I figure none of this is remotely intended but the impact it had on Sector 1 is pretty significant; I got very, very close to wiping out when fighting the Flowermen. It luckily doesn't matter at all past that point, but it does get the game off to a rough start.
Everything else is commendable. The visuals are fantastic, the music is great. The dialogue is funny and the story is intriguing. I'm not completely sure if I'd really want anything else! Great job!!
