I just bought the game, and I'm really enjoying it! I've done Joan's friendship and romance routes so far, and am now eyeing Henrik's. I'm a classicist rather than an archaeologist, so all my archaeological knowledge is a) superficial and b) completely the wrong time period, but I have several archaeologist friends, and I feel like I'm getting a little peek into their world! Though I hope they'd have more sense than to go on a dig in a foreign country without first learning some of the language...
I prefer the cave minigame to the lab one: I do those kinds of fill-in-the-squares puzzles for fun. That 'floral remains' one was bloody difficult, though! The unreliability of the lab one is a bit irritating, though at least it goes quickly.
A few SPAG errors:
Instances of 'begrudgingly' for 'grudgingly' - sorry, can't find the exact lines, but there were at least two.
'Treaded' when S is explaining the couche de merde should be 'trod'.
'Most of the kids clamored to the railing' - to 'clamour' (UK spelling - the US spelling is indeed 'clamor') is to shout, or to clamour to do something is to eagerly and probably loudly demand to do it. You don't clamour to a noun! 'Most of the kids rushed to the railing, chattering excitedly', perhaps?
And gameplay issues:
The 'Return' button from the save/load screen doesn't always work, apparently at random. Sometimes, it just doesn't act as a button, i.e. there's no mouseover response.
Henrik and Rosemarie teasing Melissa at the beginning of Week 5 about the Neanderthal ghost assumes that you spent the night in the lab building, even if you spent it at Joan and Chantal's - shouldn't that be acknowledged in the dialogue?
