Glad you're looking forward to it!
1. For now Itch will be the only place to get the Android build. When more DLCs are done we might look into getting it on Google Play.
2. The other LIs are still coming, we just don't want to focus too much on hyping those up right now since they're going to release quite a bit later and there's more current DLCs to tell people about. They'll get their time with all spotlight eventually, haha.
