Fun little zombie puzzle game! You surround zombies with matching character types to kill them. You move block to block eliminating all zombies, with a text story in between. The campaign was a good length and the characters all had some funny one-liners. It's relatively easy for the most part, although it can get intense in the later levels.

The game gives you a plethora of items to work with so as long as you use them wisely you should be good. There's also a survival mode that has you play a finite number of blocks in a specific area.

Note that although it doesn't have Steam cloud support per say, your progress is saved in the achievement stats. I was able to pickup from my 2014 save when I installed this again.
