It's been 1 month since I came up with an idea of SafeCrack! It's not original, though. Firstly it was a program by another user, you type code on keyboard and the safe opens if you're correct. I made this idea way cooler. After that, I remembered a game called "Theme bombs" (is in Play Market) with a similar idea: puzzles you need to solve to save people. After I created the number code, I remembered a few tasks from Among Us and added them. But I hope this is not considered as plagiarizmo, many people create tricky puzzles to solve. I want this project to be something creative, it's definetely similar from other by considering some puzzles as unique levels.
Anyway, 1 month is not much for a game, but a lot for such a simple idea it was at first...
