I made the character in Clip Studio Paint, animated her in pieces with Esoteric Spine and did the rest with Adobe After Effects. Aside from the stock background that I repurposed and adjusted as needed, all other assets were created and animated by myself within After Effects, Photoshop or Clip Studio Paint.

There is a version of this that depicts the “hero” character winning the game and another failing the game. There are variants of both in various formats for different devices, but also for different games (she can be seen playing an entirely different game that I recreated fake footage for).
