Great game 1 suggestion tho

So I like the game in general, it does what it was intended to do but I kinda wish that you could change the siren box to another type (like fire engine q2b pedals or something) but still it’s a great game I recommend it to anyone wanting an app sounding like a siren

Good but can be more realistic..

I think everyone here would agree, you need to make it W A Y more real. Like on real sirens like these, you can program each sound to what you want it to be. So you should add the option to where you can change the position of the siren sound to another button. I would like to see some new tones as well. Such as: (all these are Whelen" Warble, Woop, Mech Simulated, hyper Yelp(faster Yelp), and two manuals. One like the one on there now. And one that had a rise and fall like a federal q. Also, make the horn better. Make it so that if you press it while ANY tone is on, the tone is silenced but still keeps going to make it realistic.

How you have fallen to greed

Charging someone for something they already paid for is not ok, if it was a subscription it would be different. In the "original" you said pay $6.00 for full access to the app. But now you are charging again like I never had the app. It is still the same app as it was before, just a minor upgrade. I used this app often but now I have to settle for cheaper versions, why aren't you listening. Everyday your rating goes down. That top "58" game status in Europe is going away fast. Change it for your own good.
