I did do an ad-supported version for Android, but it also didn't do very well. I even did an ad campaign for it. My return on it has been ~$1.00 USD. Of course, if it went viral for some reason (I highly doubt it, but hey, I can dream) - then maybe the story would be different. It was never really designed for mobile but it does play pretty decent on the phones and tablets. I had to cut some corners to get the performance to run well (mainly I had to cut back on the particle systems). Anyway - I'd be happy to discuss. You can always try to look me up on steemit.chat if you want to discuss.
