Thank you! So far, zero money advertising it! But it is getting organic sales in the Google Play (Android), about 20-30 sales per day. The free version (a 2 stages demo version, no intrusive ads, no iap), has more than 5k downloads in 3 weeks. This site has helped immensely: http://www.slidedb.com/games/foxone Where it has been very high-ranked. However, in iTunes, it was featured in the first two days, where it got nearly 200 sales of the full version, then it dropped to barely 4 units sold per day. It had a orientation issue with iOS 8 (we fixed it in latest version) and it got a below average review from an angry customer, I think this has impacted and hurt a lot the prospect in iTunes.
