I have all the enemies I need to make the first demo. There are a few more things I need to program in and a bug or two to remove, still, but because I thought ahead and did all the level design assets ahead of time, I have everything I need to start building a stage.
I can't promise it will be done next month, because I still need something to make level-building take less time. I still want a lot of scenery, but I can't do it one tile at a time. It takes too long.
But as long as everything goes relatively bug free, It's looking good for next month.
