Greetings, sir. I believe I could be of great assistance to you on your project. I am a professional musician and audio engineer with more than 10 years of experience in those fields.
I would gladly help you out with making new sounds for your app game. It seems like a fun game and logic says that it should be very upbeat with music and I might have some perfect stuff for that.
We would work on it together, of course, I would gladly hear out your ideas and suggestions. I've been working on the Birdsbeep app sounds and ringtones just until yesterday, finishing it perfectly, as you can see on my profile, if you click on it.
If you are interested in working with me, feel free to contact me for further info regarding your project, I would be very glad to help you out!
Best regards,
Bojan
