Can you escape? (DeepWaterGames)

This is the first game I made. It is a 3d game where you have to search for clues to escape from an island. Please let me know if you find any bugs and tell me what I can do better. I tried to get this game run in browser, but the fps were trash, so you have to download this game. Tipp: Search for the portal in the beginning and look around you.

Since the graphics are quite good, the game does not run well on low end PCs.
