Tappy chicken is actually a good candidate for packaging only the ETC1 texture format.
ETC1 is supported by all Android devices, so if you have a game that isn’t using a lot of alpha textures, you should try packaging only ETC1.
The downside to ETC1 is that textures with alpha don’t get compressed at all. But in the case of Tappy Chicken, it’s a good choice.
For games where ETC1 isn’t a great option, the Google store lets you have multiple versions of your download filtered by texture type. So you would package each of the formats on their own and upload them independently.
