This is a unique game. I absolutely loved the model of the character in the spacesuit. If you make plushies of that it will sell like hot cakes.
I found the lack of tutorial and keymaps a little confusing, especially in the beginning. I found the dialogues a bit too long with no way to skip a bit frustrating. Lastly, tasks like fixing the space capsule take a bit long, like 30-40 secs?
The face models are stuff of nightmares and I hope you never change that. Other than that, good game & good luck :)
