Rapid Tap

Rapid Tap is a free-to-play casual grid-tapping game that launched on January 22, 2018. The developer, a solo indie dev at Wolfborg Games, shipped a multiplayer open beta on August 21, 2018, and then released the full multiplayer update on September 24, 2018 — the last known communication from the developer. That update added multiplayer, a new leaderboard system, and bug fixes. The store description references skins as a feature ("Now with a bunch of fun skins!"), suggesting some cosmetic content was added at some point. There have been no developer posts, announcements, or updates of any kind since September 24, 2018. With over seven years of silence and no announced future content, no unreleased DLC, and no roadmap, the game appears to have launched and concluded its brief post-launch update cycle as a small, complete casual title.
