good game but
the game is too easy
and should be sandbox mode
and diffrent things
1.blocks that cant be shrunk
2.blocks that only grow(cant shrink(
3.add points maybe some coins you can collect what opens a bonus level or something
4.maybe some obsticles like holes in the floor or zones where you cant shrink or grow
bug
last level you dont need to get the ball to end you can just shrink everything and expand the last 2 triangles should push it
