What's different? Look at the second & third images. See the directional arrows? Actually, we've seen those before too.
What's really new? You can create your own levels and play levels from other people.
Beyond Annoying: I took a break and later restarted at level 58. Somewhere around level 64, I died. I restarted....but it sent me back to level 58. No, No, No, I thought. Let's go back to the menu & select the proper level. Just doing that - I lost another life.
How bad is this? A whole bunch of levels, 10 moves are given, implying that this one is tricky. Yet I only used 3 moves.
There are 101 levels and I've solved about 72 levels.
If you've never played one of these games before, I suppose Monster Swipe is alright. The monsters are kind of cute.
Really, you should play Woodhead. It's similar, but with a touch of class mixed with wonderful irreverence.
Update 3/24/15: I'm stuck on level 77.
