 In order to make money from Frog Fractions , Crawford first sold the game 's soundtrack , with part of the proceeds going to the game 's music team . He later decided to sell T @-@ shirts containing jokes from the game in order to benefit its art team . While developing Frog Fractions , Crawford said that he came up with a lot of other video game ideas , but he then realized that he could implement them immediately into Frog Fractions rather than start a new project , due to the game 's unpredictable nature .
