Thank you! I was much more ambitious at the start, but well not enough time to go further. Regarding collisions, I agree they are bad : unfortunately, the game engine doesn't include a collision detector, and I was too busy to be able to make a more complex one.
The sound design is the part of Jessica Robo and is beautiful indeed!
(PS : I tested your game yesterday, it's really nice too. Love the coffee / snow combination and the overall vibe)
