 The team decided on using the "Fighter Maker 2D" game engine, despite having no prior experience with the software.After getting in the basics of having characters hit one another, they discovered that they could get the engine to include wall bounces—the rebounding of a character from walls at the edges of the screen—which according to Ellinghaus, show "the potential for both the game and the team".Much of the development work was spent in trying to achieve certain effects within the "Fighter Maker" engine, referred to by the team as "taming" the engine.
