Possible solutions: 1) Mozilla Firefox - settings - privacy - change to "Firefox will - remember history". It will allow to save game savings. You can use similar approach with other browsers. 2) Google Flash Global Privacy Settings panel - Global Storage Settings - Allow to store up to 10MB - reopen browser. It will not restore this corrupted save, but should help with the future savings.
Thank you for loving my work. If you liked 'In Memory' you can check my new game, 'Day In Dementia', handdrawn with pencil on paper. I hope you'll like it, and feel free to leave a comment. Enjoy your play, cheers! :) Link to the game, or just check it out on my profile - https://www.kongregate.com/games/Crobbit88/day-in-dementia
