Wow, for your first ever game this is incredibly well made. Nice to see a game with a focus on story and exploration over combat and the writing was pretty funny. The ending was impressive - you clearly put a lot of effort into it and the visuals were stunning during the warp drive, I'd love to see where you go with this one!
Loved the lockpicking mechanic (I've recently started playing Skyrim again... so it made me laugh to see a similar mechanic here), though I would have preferred using A/D or left/right to adjust the pick.
Lighting and level design was great too, really reminds me of the original Half Life, and cool to see you added slopes to add a bit of variety to navigating the levels Getting zapped and thrown backwards by the electricty was a cool and cinematic addition too, rather than being locked to the grid the whole time.
Awesome game, and looking forward to seeing what you do with this!
