Very solid overall! Definitely some fun and unique ideas, and the gimmick of the exit being open the whole time was perfectly goofy. 

**Spoilers follow**

I didn't have a huge problem with the double numpad entry; it was something I got around to trying once I ran out of other things to do, but I definitely understand other commenters' frustration with it. However, I 100% agree that the numpad light control was unnecessarily esoteric; the obtuse control scheme didn't feel intentional or solvable during play even if it was designed to be, which made it feel very annoying to me.

As for the good, I really liked the light as a puzzle element! Suuuper clever for element reuse and hiding information around the environment. Also really enjoyed the box letter puzzle, that was really neat! Also thought it was cool to use the tic-tac-toe board to convey numpad button locations, that sort of slightly expectation-breaking solution is perfect escape room material!
