Hey thanks for the compliment, I'm really glad you've been enjoying the game. And don't worry, I don't mind answering questions about this sort of thing even though we do get it a lot. If you're thinking about playing Polarity: there's already a few hours of content, but there will definitely be a long wait before you get any more updates for the game... and to make matters worse, it leaves players on a pretty significant cliffhanger (I didn't do this on purpose, haha).
While I do plan to continue work on and finish Polarity when I am able, it's going to be a long time, potentially years before I'm able to do so. The reason is because our sole focus is currently on Radiant, and developing that takes a lot of time and effort, more than I ever expected it to. If having to wait is something you don't want, then I would recommend holding off on playing it, as the wait will be a long one.
