Yes, I played through again and beat it this time with a lot more ease than the first one, and I felt like I was being a little too harsh.
I want to say, that I think your art looks very good, and I like the palette that was chosen.
Looking back, and knowing what was and what isn't intentional, I think the main problem is a lack of feedback and tutorials. I think there needs to be a couple more tutorial levels at the beginning that demonstrate and reinforce that jumping is more akin to a projectile rather than flying.
I think the idea of each egg having its own trajectory and unique advantages and disadvantages is a really cool one, but I wasn't aware that they had different trajectories and so it just felt like the game was being buggy to me.
