Earth's Last Guardian

You play as an average guy, living with your sister after a worldwide pandemic wipes out 96 % of the world’s population. After your uncle dies a mysterious letter appears in your room, as soon as you finish reading the letter a strange door materializes in your room, drawn to the door you cannot help but to open it and step through. And so, starts your adventure, you will meet many new friends and a great many new enemies. How you play the game is mostly left up to you, you can play it out on earth ignoring the strange dimension through the doorway or spend your time in their and finding out the legacy of your family and the guardian that came before you. A small hint to progress past the town being the only thing unlocked: There is content that unlocks after day 2 (it is a somewhat random trigger) keep an eye on the desk in your bedroom. Once you have been through this scene there is another break of 2 days (could take longer) where the MC thinks things over and decides what he is going to do. Use the breaks to work and buy food, this will be useful once the dungeon is unlocked. Saves are not compatible with new versions of the game, as much as I wanted to prevent this from being the case it introduces far too many bugs and issues to allow saves from previous versions.
