Nice art!!! This game would have been great with atmospheric ocean waves and seagulls singing!!
I have some feedback for you:
1) The clouds seem to be a repeating texture and i can "see" the reset happening. Not sure how Unity handles the scrolling of textures but maybe you could wait till one of the clouds are completely off screen to move back to the top to give it a more clean scroll
2) The water makes me a little dizzy but only if im looking at it haha!
3) The bird's hit box is a little unclear as I feel like im going to dodge the razors but i hit them unexpectedly for my personal taste
Great entry especially for a 2nd game jam!!
