We have improved the level design of level 3-3, added:

1) Large trees

2) Big snowmen: two types

3) New mountains in the background

4) New forest in the background

5) Wooden signs in human height

6) Support for three backgrounds: sky, mountains, forest (previously there were two - the sky and the mountains were combined), they scroll at different speeds

These improvements will be available in the next release of the game!
