After neglecting my dev log a bit, here's a big update:
Asset creation has taken up the majority of the time developing the game thusfar. I have several chiptune songs composed for the game and a number of assets drawn up including some spaceships and widget skins.
In code I have menus and some interfaces to define behaviour of the various game objects.
Over the next two days I intend to program in the templates for how the actual playable levels will work along with success and fail states.
