 (I would honestly spend money on good DLCS and not like it is now, I just get a mod apk via an app and done, but for dlscs I would give money out to be exact about 1€ up to 35€ maybe 40€.
Also, advertising sucks, I'd rather pay 2 - 5€ for the game than constantly get ads that you can remove on the side with Lucky patcher or a vpn....)

In itself it is understandable that you want to make money which I can also understand, but the in app purchases and the advertising as they are now make everything only worse than the game could be, ie there is a lot of potential.
