I loved the art and the story!! I was really sad that the game ended when I used the car keys with the car that I tried that several times to see if I could progress a little more. Congratulations, this game has a lot of potential, and the biggest step you have already done which is putting things together and make them work.
I would recommend a less sad music, since this is an adventure and you want some suspense and adventurous spirit going on. Also, some additional music for the cutscene from the start of the game would give the right mood to the player.
All in all, I enjoyed the experience from what you got. Thanks for the submission! I'll keep close to see the progress, I'm interested in this :-)
