Placial - Multiplayer game creation

Built entirely on a phone

From prompt to multiplayer in under an hour.

Melih created this flappy-style multiplayer game from scratch using only the Placial mobile app. Placial built the draft, ran a live server, tested it with a second multiplayer client and kept iterating until the game was ready to share.

Placial handles every step itself.

Placial plays the game before it is done.

Placial creates a draft, plays it, finds what is broken, fixes it, then plays it again. For multiplayer games, it can test the flow in a real multiplayer session with up to four real players before the draft is ready to share.
