I had no idea how to play for awhile till I realised the spiky barriers were moving as I did and then I could see that as the player moved so did the level. Maybe it could do with another background to make it clearer that you move across it?
I added a background today and made camera movement somewhat less snappy; hopefully this issue is addressed.
Great work!! nice background too I can see that I'm moving through space but it's till minimalistic and matches the style
