Started playing, and thoroughly enjoy discovering others beautiful photos, while being discovered at the same time. It feels great to get 300 vote-ups on a picture you’re proud of, and its so fun, and a great pastime, swiping through neat works by everyone else, too. However, after completing challenges at elite and all-star level, and gaining GS points (which are like an experience value), I was excited to move up to Challenger level, knowing I had all the requirements to do so. But then I noticed I needed to make 2 more successful “swaps”, which is a paid for ability in-game, that allows you to swap a photo out for another in the middle of a challenge, in order to enhance how many votes you might get. But I can’t do this, because I only have one swap, not two. Now, granted, its a small in-game purchase to get one swap, and I wasn’t unaware of the fact that this game offered in-game purchases in the first place. The problem I have with it, is the next level, I’ll have to complete five successful swaps, which I will have to pay for, yet again. Its very frustrating, to complete requirements for level advancement, but lack one thing which is just a money grab. Anyway, regardless of this, I will happily continue to play. Its a great concept and game experience, for those who love color palettes and photography. Get it – its fun... and frustrating.
