Unfortunately I have to announce that Pumpkin Breaker will be delayed by a whole year and expected to be released shortly before Halloween 2020. The reason behind this is that I am not satisfied with the game's current state and due to some mismanagement from my part I have run out of development time. Since this is a heavily Halloween themed game I think it won't make much sense releasing it a few weeks after Halloween.
I will try to ask Valve to update the release date, but due to recent changes regarding to release date abusers this is not guaranteed.
