Thanks for the feedback :)
The problem is that I used parallax for the foreground elements. If I had had time I would have done the foregrounds 1-1 to the level to ensure that water and spikes were always easy to see. Like this I had to try to find a balance between showing off the foreground elements, having the water/spikes very visible and having enough vertical space on the screen. Clear that ended up not being good enough.
I'm glad you liked to combat though!
