So, this is a very weird game that i just remembered. It was a visual novel, it was about a guy that whenever he came he changed bodies, I cant remember exactly but i think that he also changed time period if i am not mistaken, teh title had something like "i dont care" or something in it, but its very vague of a memory so i cant find anything, it is somewhat old but i remember enjoying it
