Hi there!
My thoughts of the screenshot:
- I like the background, it has a nice playful look!
- I also agree with brynn, the eggs could look better. I was able to see them as eggs, and also saw the legs, but when the graphic is smaller, they just have black dots and do look like a bit like soccer-balls. I don't know, but to me this game seems like a candy crush thing, where you have to math three eggs of the same color by switching two positions? Well and apperently all of that, without any gravity... If that is the case, consider removing the wholes. There are a lot of possiblities giving the user a hint, that there are two eggs of the same color. They could for example shake a bit, like they try to hatch, but just can't (because there is one egg missing).
- Your background squares are actually not squares, if you take a close look at the screenshot:

This is (at least for me) really irritating considering that all squares are in a grid.
€Dit: I just took another look at it, maybe you also did it on purpose to create a bit of a 3d-Feeling, than make the effect way stronger, so that is noticable.
- I don't like the stripes inside of the stars, they are not very consistent, compared to the rest of the UI. Also consider not showing them at all. I think it is no coincidence that all big games show the users their earned stars, at the very end of the level. It is way more rewarding, to see them pop up at the end. Using stars as a point counter kind of destorys the magic. Use a normal point counter instead, to give the useer feedback, how good he is.
- The costs of the actions is a bit hidden and also too near to the edge of the scrren, try to integrate the costs inside of the button.
- This is probably my most important point: With those graphics, you can have a successful game, what really is important are the animations and the polishing. Try to get as many animations as possible in there. Cut the rope is an excellent example for that, take a look at a video (for example this one:
http://youtu.be/pFDS2oFmugs?t=5m4s) and try to find all animations in there, look what happens in the bakcground, or what the green thing does, when the player collects a star. All of those animations are super important for the look and feel of the game!
Good luck, looking forward seeing more of your game
