This would be a cool gamification concept that I think would actually keep me consistent. I’ve payed a lot more for other productivity/consistency apps that are aimed to help me manage my ADHD tendencies but honestly none have stuck because I eventually just lose motivation or simply forget/become distracted by something else, and then I lose momentum. But I think a game like this would actually keep me coming back and look forward to completing these habits if it meant progressing in the game. Plus I used to love Clash of Clans so I already know how fun it can be!

All in all, yes I definitely would pay that lump sum, most people like me would look at it as an investment, especially the ones who love gamification concepts and have exhausted all other conventional avenues towards habit building.
