Hate the ending

Went into this show knowing nothing about it. After arisus besties die I’m like Holy Fuck this is a good show. Second to last episode all the main characters get maimed down but they are “somehow still alive”? And then it turns out that it’s all just a meteorite like BRO. Literally would have rather the ending be he created the games to cope with his friends dying right in front of him

side note: Is the manga any good? I’ve seen some panels and I don’t like the art style LOL
