I love me a good point and click game, and when you add space to the equation I instantly become ten times more invested!
This really is a gripping tale, and I'm really curious to know what the overarching story is and where it will go from here. There's a lot of great things being set up here, like why SOL is acting kind of suspicious, where the heck Dr. DY is hiding out and why we can apparently survive in the vacuum of space with no suit... all important questions that need to be answered!
The only small gripe I have is that the sentence structure and grammar is a bit shaky at times, and if you want to hit a big audience and look professional that will need tidying up a bit, which is easily done with the right help (I saw this mentioned below too, so I know you know about it!)
Anyway, loved the demo, will definitely be looking forward to playing more and keep up the awesome work =)
