Four years of solo development by an unknown creator. When that effort led to success and he shared the news with his wife, the story of this developer’s surreal daily life and happiness became a viral sensation in international online communities.

On March 9, solo developer Cakez released 'Tangy TD,' a tower defense game he had spent four years building alone, on Steam. On the day of the launch, he opened his Steam dashboard to check the daily revenue and burst into tears. The game had earned $31,942—roughly 47 million Korean won. He shared this moment with his wife, and the two embraced, weeping together.

This scene was broadcast live to his viewers. Throughout the four-year development period, Cakez had consistently shared his entire process via live streams. Viewers who had followed that journey, along with others who discovered the story online, naturally became interested in the game. One week later, the reported revenue reached $245,000, with a net profit of $197,000 from over 28,000 copies sold. Tearfully, Cakez expressed his gratitude for the kindness of those who supported him through their purchases and encouragement, humbly stating that he did not deserve such overwhelming support.

One month after launch, Tangy TD had generated over $600,000 in net profit. He revealed this milestone on his stream as well, watching the numbers climb alongside his wife. This time, seeing his wife smile with pure joy and kiss his cheek, Cakez expressed his happiness, noting how proud she was of him.

Tangy TD is a pixel-art tower defense game that Cakez built from scratch without using a third-party game engine. Beyond its technical achievement, the game has proven that its success was not merely a result of viral marketing; it boasts an average playtime of 1 hour and 15 minutes and maintains a 'Very Positive' rating on Steam, with 92% positive reviews from over 1,200 users.

With news dominated by games selling millions of copies and nearly 20,000 games released every year, the success of a solo-developed title without a publisher is truly special. While some might attribute this achievement solely to luck or global viral trends, others point out that his consistent, transparent documentation of the development process served as effective marketing. Regardless of such external analysis, there is no doubt that Cakez’s success and his tears of joy have warmed the hearts of those who cheered him on.
