My thoughts on this short-but-sweet game:
Love the thematic elements that used the ASCII display in unexpected ways -- the styling was great; despite everything rendered by mono-spaced characters (Dwarf Fortress, anybody?) everything always felt very fluid.
As for the gameplay, it always evolved without overstaying its welcome. New mechanics were seamlessly integrated without feeling like an afterthought and none felt needlessly tedious.
Some of the later levels were quite tough, not because of the planning involved behind the puzzles, but because the lasers led for some VERY short windows of opportunity. I have a very fast typing speed and even I had to retry a few times.
The worldbuilding is great and the ending left me craving for more about the scenario. The characters do feel like real personalities, although at times they seemed a bit hackneyed. But I feel like that's more of a subjective bias on my end.
I'm not sure if the concept would hold water if made into a full game. But for its current length: just perfect! Thank you for this experience!
