There is a little bad news, and GREAT news is happening in May.
First, for the little bad news, I'm currently focusing on taking screenshots of all the Alpha Levels for the game and converting them into these 2D maps for me and my level designer can look over so we can plan out the updates and changes that all the levels need. So haven't got around to making updates on the levels themselves so it might be during the mid or near the end of the month that a new playable build be available.
But for the Great news, I am planning to give Tsinji some extra funding so he'll be able to do some Wrapturous Adventure work almost every day during May. So while it might be a few weeks till the next playable build you will at least be getting to see a couple of new in-game artwork for the game in May.
