Hi,
that's a great idea, minesweeper games on their own, except beating the clock, give not so much will to go on and on and on except for a quick, quite relaxing, game from time to time. Giving long term goals, tasks even maybe, is a great addition. I like when a nice game teach you something at the same time (like some game about chocolate based bakery and trading goods I don't remember the name I played long ago).
From the last dev log although, it looks like there are too much focus on museum/dinosaur/collecting/assembling stuff and not so much on mine sweeping, which, I suppose, is still the core of the game, you may have to be careful with that and don't neglect the core part.
Also, from devlog 6 video, the mine sweeping game looks odd to me, I see blank space filled with "dirt", I guess, and a number, it doesn't look natural, I mean, all area could be dirt covered and when player dig a cell, dirt is removed, showing either a number, nothing, a bone or whatever.
Finally, you're update just popped up at the right time 🙂, I think of hexceed (available for free on Steam), it's a nice game still the author completely forgot about the will to play, it's always the same kind of field to clear, same obstacles or hints and there is no progress along the way, making it pretty boring as nothing push, or kick in the back, the player to go on and go on and always discover new things and want more, which is the base of a good game.
