Clan Run - Race and Clash against Goblins and Dragon Clans

I had to test this as part of my work. The icon caught my eye in AppStore and I had no expectations to one way or the other. Unfortunately this game has too simple game mechanics with uninteresting theme/visuals to keep my interest. It looks like this game was made in a high school programming course. The lack of polishing and poor level design made me quit after 17min 30sec play (our standard testing time which is divided to smaller sections). Overall experience was very frustrating and negative. The gameplay does not elicit curiosity to continue. Lots of ads between transitions in the menu. Also, the game hides the IAP prices which are revealed only when you confirm purchase.
