Is there a way to open any of the doors?

'E' at the computer terminal.

The game brought tension out well. At one time I thought the text in the corner was something moving while turning. The sterile atmosphere was really enjoyable.

If I was to give any constructive criticism, I would suggest giving a little more feedback when the player works with a computer. I wasn't sure if my interactions when pressing the E key did anything. Otherwise a well-constructed piece!

This made me depressed :(

Glad you guys liked it, we're planning on making a full version with all of original ideas implemented.

Mood is good, art is nice (and fact that you've coded everything from scratch is a big bonus), but I kinda miss some more fun / gameplay here. What's really bad is you don't tell player how to control the game (if not for your explanation in comments, I would probably tried E, but since there's no feedback that pressing E done anything...).
I gave up after picking energy core, since I found no new opened door and it didn't seem that pressing E on other stations is doing anything...

As already stated a small feedback for interacting with a terminal (even a *bleep* sound) would have helped a lot. Really liked graphics and atmosphere, good job!

pretty cool, runs well under WINE also, i take it there's nothing else to do once out on the moon?

In the future, space bases will be organized so that every function of the engineering core will be placed in a separate, identical looking room. This will make engineers run around and get fit while doing their jobs :-P

Nice graphics, but the game felt more like a demo. I was very lost until reading the comments and realizing the "E" key existed -- you need either to give the commands to the players in-game, or provide some feedback when the player just try mashing all the buttons.

To Raptor85, yeah the moon was supposed to be the beginning of the second stage, but became the ending.

To caranha, in my panicked rush I told myself Half-life controls would be everyone's default go to control style for first person games. Really I think it's just mine. This mistake will definitely be corrected on re-release and won't be repeated for future entries.

Beautiful aesthetics and sound. The gameplay fell short, but you have a great base to expand upon.

I never knew game maker could render 3D graphics like this. I just wished the gameplay was more elaborated.

I absolutely adore the artwork!

As others have stated, the mood is great, but the game is let down by the lack of... game!
I'm far from someone who should criticise a game for not being interactive enough (people in glass houses, etc.), but I think if you're going to go for more of an interactive story environment then you need to give the environment more of a personality. It started out great, and I love the graphics style and the quirky little music snippets. I was disappointed that the entire base looked the same, though. There were no real landmarks in the entire building to help me find my way around, and that was what made what little gameplay there was feel tedious.
Just my 2-cents, of course, but I think if you concentrate on making the environment the main character then you've got the start of a great game here.
