[IOS] [unknown] Weird Minecraft space ripoff

Ok, so when i had this old iPhone when i was i think 14 or 13, we didn't have a copy of Minecraft and i couldn't buy it on it, so i got this bootleg version on Minecraft but it was set in space..and when you dug underground there were randomly generated bunkers..it was really low quality and was really confusing..everything was a light tint of blue or grey, i mainly played on creative..idk what the game was called but thats kind of all i remember..i think i downloaded it on my moms phone but she got a new one..need help remembering my childhood and this weird game
