I submitted Removr 1.3.1 early last week and it’s been in review since Thursday 2/10. After 1.3.1, I have another minor update that will look for additional levels in the documents folder as well as support for purchasing additional levels.
In the future there will be two ways to expand levels. You can use the level editor and add leveldb files through iTunes file sharing, and eventually I’ll have in-app purchase for new level packs. The previous version copied the level database into the document directory, where it was accessible through iTunes. That was not a good solution since app updates which changed the levels would wipe out your changes, and it was possible to mess up the levels. It now only adds levels found in the document directory to the existing levels.
