The art style is phenomanel and also respect that you coded everything "from scratch".
The only thing that bothered me was, that I could not use the keyboard, there the game would not start upon pressing enter. Also the timer doesnt really add anything to the game. The Game already is interesting enough without the timer. I dont see why limiting the time for the player is useful, since it just complicates exploring the game world.
Still: very cool game!
