I haven't seen an update to frozen free fall for a while. I checked the store on my phone in the last few days and frozen free fall is no longer available as an app to download. I've since checked frozen free fall app page on the windows phone website and there was an update on 26/6/2015 which I didn't receive. When looking at the page online it now says not available for all phones. I have a device with 512mb ram. I'm now guessing that frozen free fall doesn't support 512mb ram devices anymore? If that's true it's a shame.
