There's good and bad in this puzzle app game.
I like the submarine, helicopter and lunar rover pushing the blocks. Good graphics. Playful.
Something new: I think this is the first sokoban puzzle which has some targets hidden by blocks. In particular, I thought level 30 was quite challenging because there were only 2 targets and finding them was a preliminary challenge. I doubt whether anyone could solve that on a first attempt. Unless by pure luck.
The more interesting of the 54 levels have specific targets for specific tiles.
I downloaded the free version which offers 36 puzzles. Solved them all then paid $.99 or $1.99 for the next 18 levels.
The author, Grettel Monteagudo Garc'ia, has taken some liberties. As I said at the top, I've solved countless sokoban levels in other games over the years. It's impossible to remember each one. However, Grettel has copied levels 37, 44, and 51. Howe do I know? Because I struggled on those mightily and had to truly study them. I believe those came from BoxWorld.
Level 54, I'm fairly certain, is original and good for Grettel. Grettel, don't be lazy! Remove those that aren't original and add new ones.
