This game is really impressive, in its own way. I'm surprised by the amount of options the game has for some parts. I like the core idea behind it, that the player has to prepare in time before the final test.
Though I think it's pretty unlikely to finish it in the first playthrough since you need to know some tricks, timings and all the stuff. Which can be fine: could be an incentive to play again. If that's the reason though, the length of everything might be a little too much - having to replay all the first 5 days just to be more prepared can be a little tiresome, considering that - even if you can learn more tricks - the game never changes, it's not a roguelike.
Also the Black Mountain section was way too long this. If it was any other game the dungeon length would be perfect, but here it's a "preparation test", a way to check if the player built the team correctly. And having to struggle trough the first parts of the dungeon only to find a wall right after, it's a little demotivating.
The start of the game was very confusing to me, since there were too many options and there was little to no guidance. And it didn't help that this game has a lot of custom names that often were unnecessary, like giving a name to the days of the week - that was just extra confusing and I didn't really see any need for it.
Though I appreciated how you inserted new races instead of relying on the classical tropes of dwarves, orcs, ecc...
I never expected this kind of game from the jam. It's very unique, but with its flaws. I liked it a lot, so much that I tried a second playthrough on my own after the stream. But despite being very engaging, I can't bring myself in trying again, since at the end it feels like every day I'm doing so much for too little, and it's the same steps all over again, with some of the content hidden maybe too much (I never recruited Selaine even if I tried hard).
I don't think I can give the right suggestions for this game, since the concept is pretty uncommon - but the idea is very cool. I just hope you can understand what you want to be improved and what works. If that helps, here's the VOD from my stream:
Note: I tried to inform you of the stream via mail, I'm sorry you couldn't be there in time.
