Glad I'm not the only one who got contacted. The scumbag is throwing around his trademark notice and he doesn't even have one: https://www.trademarkelite.com/trademark/trademark-detail/88474539/DINO-HAZARD
Current status of trademark = "Dead"
The Dino Hazard game seems pretty dead too. He has a YouTube channel, but it's all about dinosaurs. Nothing about a dinosaur game: https://www.youtube.com/channel/UCjcEWCkuafL02yvkujCwL4w
The Steam page for the game is here: https://store.steampowered.com/app/1287540/DINO_HAZARD/
Would be a shame if it got review bombed!
