Wow, what great visuals, and with the shaders and all, it works quite well! Really loved the limited movement of this, figuring out what to do, and then the end part was great. One minor thing I will say with the Door Closest command, in the starting room, it reads "Closest Door: 0", which either means you're not near a door or the door is #0. I know there are only three doors, and fundamentally its going to always be #1, #2, and #3, but my brain was wondering why Door 0 would never open, until I tried Door 3 and it said too far away, and then it clicked. I don't think anyone else would ever have this door issue, it's just a personal failure on my part. Oh, and I wish there was audio.
Anyways, great game!
