Praise for Hang Line

Hang Line is a unique concept within the over-saturated market of games that are based around over-used concepts like base-building, gem matching, and etc. Hang Line deserves the chance to be presented to as many consumers as possible just because of its dumb-fun gameplay (no offense). In addition, I appreciate the mitigation of micro transactions within the game. This is a huge improvement when compared to other apps in the App Store.
I also love the tone of the story, the developers do not take the game too seriously, which leaves room for funny plot development like movies based around goats and mad scientists blowing stuff up. Overall, Hang Line is an addicting and “fresh” game, I hope that more content is added.

No ads, but needs more characters

Overall a really nicely done game. It’s hilarious to see your character flop around because a mountain lion tackled you or a goat kicked you. The lack of ads is awesome (other than if you try to continue vs. start the level over), because you die a lot 😂 the gadgets are cool, and make it a little easier but I never use them because the only way to get more is to purchase them with real money as far as I know. The two things keeping it from 5 stars is there needs to be more unlockables. There are a few helicopters to choose from, but only three characters? That in game currency could be used for that as well or maybe to get gadgets. Other than that the game is addictive and easy to learn, hard to master.

This game is fun and somewhat satisfying to swing from one side of a mountain to the other. Although, there is one glitch that is preventing myself and my sister from experiencing its full potential. In order to continue to play, you have to pay coins which you earn from playing the game. But, there is no other way of earning money unless you have levels to complete or the rescued survivors donate. In endless mode, you are supposedly able to earn money to unlock more levels. But, when we earn money from endless mode and return to the menu to buy a new level, the coins we just had earned have disappeared. It’s irritating that this feature doesn’t work! Please fix!
