Enjoyed, but short
As the title says, it could use a little more depth, that and I had no idea what I was doing with the numbers so I kinda fiddled around and then the game ended so it was all good I guess, loved the art style, make it longer though, it just ended too quick without too much mind bending, but still cool none the less. More keys maybe too, though using the limited number in different ways kinda made a little complex except the front page saying that you climb ladders with left and right, took the fun out of that tiny logic puzzle. Oh well whateva, good game, peace.
