It's a great first try, but I think it suffers a lot from being overwritten. I applaud the decision to make that exploration log into more of a summary of the parts that matter than a full blown log, but that same restraint isn't there for the test logs and the journals. The tests are by in large redundant with the Description and could easily be summarized into 1-3 entries.
The journals are the biggest letdown here. The visual of a botched self-trepanation is strong enough that all the ensuing explanation only dilutes its impact with the kind of "scientist makes contact with something and goes insane" plot that every Lovecraft short story is about. I think you could easily turn it around by having most of the stuff this dude says out loud be clinically-worded conclusions extracted from the scene, or suspicions about his motives, stuff like that.
2 stars. I think there's a lot of work to be done, but the core's certainly interesting and gets a lot of things right that authors generally struggle to.
