Jigsaw Slide

This is a jigsaw/puzzle game. Sliding the blocks to spell out cute pets. There are two modes: easy and hard. 
In easy mode, switching to exchange adjacent small blocks. 
In hard mode, it’s like playing a Rubik's Cube except that you can fix a block if you want. 
The higher the level, the more blocks and the greater the difficulty. 
Wish you have great fun!
