There's something pretty cool about this, honestly. The commands linked to keys is reminiscent of point-and-clicks in a way I really enjoy; it's something I'd love to see expanded on. I have some issues, mainly when it comes to collisions on doors and the like, but that's pretty understandable given the short time frame of the jam.
Of the games of yours I've seen (I may have dived in a bit...), the concept and execution of this one is probably my favorite. Like I said, I'd really only want to see it expanded on, more puzzles, more interactions... stuff like that. Great job, in any case!
