Nice work! I loved the presentation. The art style combined with the post processing and ambience music fit really well together.
I think the levels were a bit tough because you couldnt really see what obstacles were ahead of you, so on level 2 I got stuck even though I had no way of knowing I would get stuck, so it wasn't much I could have done to prevent it. Maybe you could add a restart level button if there are places you can get stuck on levels at.
Great job overall! Really impressed that you managed to create this in just 48h!
