"ButoBird" is a competitive action game where players control birds equipped with jetpacks and firearms to knock each other out of the sky. Up to four players can participate, and the trial version was available for Nintendo Switch.

The game's rules are straightforward - within a time limit, players earn points by knocking out their rivals. Before each match, players can choose a bird type and pair it with a weapon of their choice. The trial version offered balanced and speed-focused bird types and various weapons like missiles, Gatling guns, and chain guns.

Controlling the birds involves using the stick for direction and simple actions like dash, brake, and shooting. The intuitive controls make it easy to spot and chase rivals, and players can execute technical maneuvers like sharp turns using brakes and dashes.

To score points, players must first shoot opponents to make them dizzy and then dash into them for a "blast-off." Successfully blasting off rivals earns points, while the knocked-out players respawn after a few seconds. Players can also find items on the stage to recover health and manage an overheating gauge.

"ButoBird" offers easy-to-understand and engaging gameplay, with various strategic elements. The stages feature obstacles and holes to navigate, allowing players to evade enemies' pursuits or create opportunities for themselves.

Additionally, the game introduces a twist with the appearance of a special item called the "Megaphone." When collected, it triggers a mode where players must work together to take down the current leader. If successful, players other than the leader receive a substantial point boost.

The combination of exhilarating speed, simple rules, and the cooperative twist makes "ButtoBird" a fantastic party action game suitable for players of all ages. The game offers well-balanced gameplay, swift action, and abundant support for various actions like shooting and dashing, resulting in intense and enjoyable battles that kept players excited and engaged throughout the event.
