Very nicely made! The music, voice, and sound effects work very well, in my humble opinion. Not overly original, though, as this style of game has been done a lot (seemingly whenever a AAA game wants to do a "hacking" mini game or some form of "plumbing" puzzle)... none, the less, this was executed very well!
My one gripe... once a puzzle was running, there was no way to cancel out. I either had to finish the puzzle, or force quit the game. The puzzles (at least the first few) were short, so it wasn't a huge issue, but I noticed it.
