Played the first 40 levels and it's a nice enough sliding block puzzler.

It's worth a look if you like this sort of thing.

Hints and undos can be purchased for real money but levels are short and restarts are unlimited, so undos are unnecessary.

After completing 40 levels, you can pay $1.99 to open up the next 20 or wait four days for them to unlock. It looks like there are similar barriers at the 60 and 80 level marks. Slightly annoyingly, the four-day countdown restarted after upgrading the app to v1.01. It only added 30 minutes for me, but could cause pain for some.
