So, his BSky account still exists, and is still active, but there's no mention of any game development anywhere, and it seems like he manually purged any mention of whatever it was he was planning/working on. There's not much on his account currently, but considering there *was* at least one post about his remake/sequel/whatever it was, the complete absence of any hint towards its existence unfortunately seems to point toward him not being particularly enthusiastic about making it.
Hopefully I'm either wrong, or this changes, because this game was very good. Fairly basic? Yes, but still very enjoyable.
