there’s a raft mobile game, and I’m concerned your ideas been transformed into a money hog by someone who doesn’t own it, here’s a link to their Instagram page if you care to look https://instagram.com/raft_original_survival_game?igshid=1pcq3ax5a3ow7

That game and it's developer is in no way related to Redbeet Interactive. The developers are aware of it but there is little they can do about it. Mobile marked is quite literally littered with Raft clones (so far two have made it into Steam). Just go see Google Play Store and search using "raft" and "survival" as search terms in the games category. You'll be surprised.
