Evaluation
Bat Boy launched on May 25, 2023 after a successful Kickstarter campaign. Following launch, the developer shipped a notable free update on June 30, 2023 adding a new Speedrun+ game mode, and then released a series of bug-fix patches through August 31, 2023 (Patch 1.0.9), which appears to be the last developer communication of any kind. The game changed publishers to DANGEN Entertainment in March 2024, but that post was purely an announcement of the publishing transition and contains no mention of new content or ongoing development plans. The only DLC listed is the soundtrack, which was released on launch day. There are no unreleased DLC entries, no announced future content, and no roadmap. The developer has not posted any updates since August 31, 2023. Given the game's structure as a self-contained 2D action platformer with a clear beginning and end, and the absence of any post-launch content announcements, the game appears to have shipped as a complete product with post-launch polish support now concluded.
Evidence
Bat Boy officially launched on Steam on May 25, 2023 as a fully realized 2D action-platformer.
Post-launch update added a new Speedrun+ game mode and HP mechanic — the last notable content addition.

About this game
Play as Bat Boy in this 2D side-scrolling action platformer in which the interdimensional mage Lord Vicious has brainwashed Bat Boy’s fellow teammates in order to participate in the Trials of Darkness, a heinously brutal series of athletic events! It’s up to Bat Boy to team up with the mouthy crow Garou, traversing a hostile world, to free the minds of his sports-hero teammates and learn their skills before they fall victim to the Trials. Along the way, Bat Boy will encounter all manner of characters, some allies, most not, as he fights his way through the bad guys in a variety of levels until reaching the final confrontation with Lord Vicious.
Bat Boy pits the titular hero against the former allies of his sports team, heroes such as Racket Girl, Shinai Guy, Aquaria and Mr. Blitzer, among others as he travels through the many regions beyond Lord Vicious' dimensional gateway!
