Solved everything, waiting for invisible mode
Completed all the levels in all 4 games of FlowFree, solved everything in FlowFit. Needless to say, I think this game is 11/10 with comfortable UI, controls, pleasant colors and cool levels. Now, after almost 800 days of daily challenges completed, I ask the developers of one more thing – please add an invisible mode for the FlowFree games. The process would be still the same – you drag the finger to create a visible line, but after taking the finger away it becomes invisible. Just thought it would be an insane + fun new challenge – solving a 15x15 board blind. Thanks for making these games!
