Shortly after v0.20 released, we were planning on hiring someone else, but things fell through. But now, we are in the final steps of hiring a different person to help with several areas of the game's development. I consider it important for quality to stay the same (or improve), so finding the right person that we could also trust wasn't easy. We'll have more details once this is completely finalized, but you can expect this addition to significantly speed up development (after v0.21). The goal is to have an update at least every 2-3 months or so.
