16bit Sensation: Another Layer

Both have protagonists who are are passionate with game development but they got stuck in a dead end job. They get transported back in time to get a chance to redo their career. 

Cute girls doing cute things/slice of life anime, also in the game developing industry 

both anime are about creating visual novel games with bishoujos. 

Both shows share a similar premise: the protagonist, who isn't very happy with their career outlook, mysteriously time-traveled several years into the past. To prevent the same mistakes, the protagonist is motivated to dive deep into the game development industry to reach success. While both shows tried to highlight the process of developing a video game, Losing Money to Be a Tycoon focuses more on the comedic side of its characters. Qian's "Fortune Conversion System" where making a net loss in his company is more profitable for his personal gains is the source of many funny gags between him and his employees, especially how the employees misunderstood his motives and unique directions. Qian's suffering by his inability to lose money is a literal "suffering in success". Meanwhile, 16bit Sensation puts more focus on its storyline and the supernatural part, thus giving it a bit of a serious tone. Konoha's motivation to make games is driven by her deep passion for bishoujo games. Being able to travel in time back and forth to periods of phenomenal games gave her a taste of game development she would've never had, plus a chance to create her dream game from scratch during the golden era of bishoujo games. However, exploiting the knowledge of the future may have caused some unexpected side effects with her timeline. If you want light-hearted comedy to de-stress your brain while still having an entertaining plot for you to follow, then try Losing Money to Be a Tycoon. If you like Akihabara and old-school video game otaku references based on real life with some science-fiction twist, then try 16bit Sensation: Another Layer. read more
