i think that an ads system would make the game greater

From what I've seen so far, revenue from ads is rather small. I wouldn't mind that, but I don't think it's worth compared to keeping the game clean. 

Besides, some people have occasionally been kind enough to make small donations by themselves. 

Thanks for the suggestion though! 

when i said ads i meant aim down sights not advertisements sorry for not specifying 

Oh, that :) I could add it as a feature then. If I see it's easy to make, I might include it in the next update. 

thank you it would be a great improvement
