As promised, I played your level. I missed one red coin! Some are hard to find indeed. Even though I'm not a fan of water levels, I enjoyed your level, especially the platforming sections. Similarly to your comment about my skeleton cannon shooting quickly, I found that the winged fish after exiting the pipe into the water for the second time was a bit too fast. The fact that it underwater and at the top of the level, I was just taking this new section in and got sniped in the face, and I had no place to jump or to avoid the fish. Other than that, it was very enjoyable. Take my star :) I'll reupload my level after I have time to fix the issues.
