Cute style, and a game that fits the theme.
Unfortunately I was struck with a few seconds delay for every action that made especially level 7 really hard. But I guess it may be unity webbrowser thing. 
Nice work :)

a nice idea to scale the environment as the main mechanic, expect more mechanic.

Good job and please work more.

It is a nice creative idea, keep up the good work. 

the controls are very strange

The graphics are quite good even though it is sometimes clipping with the background. The level are fun but idk if the growing platform sending the slime into the ground is expected behaviour.
