Sushi Mushi


Aspyr Media, the leading publisher of Mac® games, asked AC+A to evaluate their design strategy for Sushi Mushi, with a focus on beefing up their monetization performance.

Our team identified four key factors that were preventing Sushi Mushi from reaching its full potential.

AC+A’s Solutions

First, we helped the Aspyr team to transition to a premium currency model, which allowed players to purchase packages of coins that could then be exchanged for game items. Next, our deep analysis of Sushi Mushi’s game difficulty led to a completely revamped game logic; this was designed to increase the number and frequency of monetization opportunities a user can experience during their lifetime. We then carried out a full art and UI assessment and introduced a visual styling that could compete with top-performing games. And finally, to help bolster user retention and engagement, AC+A introduced a series of light narrative elements into the game.


Sushi Mushi experienced a dramatic and sustained 165% increase in revenue per paying user, or an extra $10 per person, thanks to the new currency model. The reorganized game logic resulted in further increases in ARPPU and an increase of nearly 50% in Sushi Mushi’s conversion rate. The new graphics translated into improved player retention, and the fresh new narrative elements meant longer and deeper first-time player sessions.

  • "My team has been actively implementing all the ideas Adrian’s group suggested, and I am already seeing positive results with 4x ARPPU numbers than before our engagement. They easily integrated into our team and felt more like team members than outside consultants. In short, hire AC+A for a few months; you will not regret it."
