"Astronauturon" feels like the sort of word a native thinker couldn't figure out, or that we might dismiss as too odd. But it works, a portmanteau of astronaut and Adventuron, presumably. It's far less plain than "A Mission in Time." Though the execution itself isn't especially snazzy, for better or worse: you're in a dark forest with a lot of rooms, but it's not really overwhelming. You're an astronaut coming back down to Earth, which humanity fled when it was irratiated, but after a hundred years, it's relatively safe again.
Well, except for that bear chasing you around the map. I didn't get caught by it, but some red text indicated it was nearby, as I took photos of artifacts with my camera. Then I went back to the ship and uploaded them, which presented the main game puzzle: there's a time capsule hidden outside the initial rooms you can view, and since your inventory capacity is two (three, if you drop the camera,) and there are six items on the photograph which you now recognize, you need to decide what is most practical.
This part is not very taxing, but recovering the time capsule is effective, and of course, when you win, you see what's in it. The ending is a bit cute, maybe too cute for the general mood, but it wrapped things up nicely.
Astronauturon is not a crushing experience, nor an unfriendly one, and the mapping goes quickly. But it feels like there could've been more puzzles with the items you find in the house, and the camera mechanic could have been used more. I feel like I may have missed something during my quick playthrough. I quickly went from being worried the map would be too tangled to wishing there was a bit more to do. But it works, and the black and white graphics are a neat touch that help emphasize the red text without overdoing it.
