Ximad’s Pandas vs Ninjas was previously available as a paid game (at $1) and has now been accompanied by a free version. They acknowledge that it’s an Angry Bird’s clone, except it’s uhm…pandas and ninjas instead of birds and pigs. The paid version currently has 4.5 stars and overall very positive reviews but it lacked a trial mode. The free version has ads so you can use that as the trial mode or pay the $1 to remove them. Sweet.
