Good things:
All each puzzle is different, with no repetitions.
Good graphics (for be an 8-bit game).
A fullscreen mode.
A main character that reminds to Yoshi (Mario Bros)
You can mute if you want.

Bad things:
Music is only on some levels.
There is no pause mode.
I played like 50 levels and I stopped there. When I tried to continue, I had to restart. Please fix that.
Some levels are all timing.
I'll give it a total of 4 stars.
