Thanks I agree, still debating on whether or not I want to announce the 4th project once I finish this one or if I should wait until I'm almost finished with the 4th to announce it.
In my opinion it's probably on the safer side to announce the 4th project when you're completely done with the current one you're working on. As to not have any potential people badgering you.
Truuuue, I'll most likely release the 4th demo near the full 4th game release date as well. Demo release + full release date a month later might be the plan going forward.
