Review of I'm Standing on a Million Lives

This anime follows protagonists summoned by a god and the world is facing destruction within three months. Each protagonist has personal struggles. They must solve challenging riddles within a time limit to get abilities in a world where time goes faster. As the complete the challenge they get sent the their world and back days later and meet friends that have grown older in their quest to complete more riddles and overcome their struggles and their odd friendship becomes normal over time. Think the show is alright is is different from isekai that i have seen The Opening is a BANGER imo!!!
