As I've mentioned prior on the Steam store page, the game being released does not mean I will stop developing it. As it is, it is a finished game, but I find that adding levels and other features will be a good way to show that I am committed to ensuring the game is as good as it possibly can be.
So in order to prepare the game for the next update, I have finally gotten around to moving the game from Unity 5.5 to Unity 2017.2, which means that some of the assets I use have been updated and will be better optimized. It also means I need to rebake all the lighting on levels :P But that should be a fairly quick process, albeit with a lot of manual meddling.
Come this weekend I will post news on how the update is progressing.
