VT on Kindle Fire HD7 not available?

Hi! So excited about the release of Virtual Town. I see the app in Amazon's app store, however, it says it's not available. Any reason why that might be?

Essentially, we removed certain devices from the device compatibility list to prevent downloads on older devices that may not run the game well.

We're working on final testing of the fixes that should allow Virtual Town to run well on older devices. Once we have finished our testing, we will release the update to Amazon and update the device compatibility list so that you will be able to download it.

We appreciate your patience as we work on this.

Thanks, any eta?
