Here is my feedback from playing this game for the finals as well:
Overall a really enjoyable puzzle game. I liked how DORIS would aid you if you did awful in the puzzles, as I never did get that stealth puzzle at the beginning. I did not care for the 10 second timer to get past some puzzles, but it was a really minor quibble in the end.
Overall though this was a fun game to play, and I managed to get to the end in under an hour. Good job on making a game that got to the finals for the IGMC!
