It was definitely the biggest inspiration I used. Suspiciously so. I mean, I certainly didn’t set out thinking: “Right, I like that game. I’ll take it”. It just stuck with me. There’s a line between paying homage, or being inspired by and while I tried to sneakily tip toe across it, I wouldn’t be surprised in the slightest for being called a rip off. That being said, the games are completely different. Not only in look or in tone, but at the core. ‘Every Day…’ is about the monotony of life and work, while ‘Once Chance’ is about a bearded doctor trying to save his family. I guess the morning routine of people going to work is just a good way to identify with people.
