One suggestion I have is to upload new areas complete with all the enemy sprites and then add in the area's Game Overs in 2 or so smaller updates.
Since it takes longer to draw GO's than the sprites, updates that consist of a large number of them like the April update can take months to come out. Breaking them into halves can help us feel like the content is coming at a constant pace and you would probably get less messages asking if the game is still being worked on or "are you still alive?". True the pulse updates help in that regard but not everyone follows those even if they should.
