Thanks for checking in :) I've started development quite a while ago but you're right that I haven't been communicating many details. This is less of a "more stages more weapons" thing but more of a full game since the current version was a gamejam prototype.
Everything is still in flux which is a big reason why I haven't given any specifics, but there are many new features in the works. Wish I could go faster but I'm still learning a lot myself.
