Fair enough on having an opinion—and yes, the release date has shifted on multiple occasions, for which a public apology has been made every time. Feedback about Arvus games is always welcome, but your comments aren't actually about the game itself; they're about demanding a timeline on your terms.
Suggesting you'd "prefer cancellation" over waiting isn't constructive feedback—it's saying that if the timeline doesn't suit you personally, you would rather the game be abandoned and that no one else in the community gets to play it either.
You are investing patience; Kal is investing time, labor, and resources that could be going into Roundscape, but is choosing to put them into Starmaker so the community gets a polished final product. Updates are delayed to ensure quality, not to "string people along." You are more than welcome to wait for the final release, but the timeline remains Kal's to manage.
