If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Play the new unity 3D game Cavern0048. The game doesn't enjoy impressive graphics but the movements and schemes you can do are successful. Use arrow keys to move and to make new moves that will bring you more points. The more complex movements you do will get you more points. Finish the race with a high score and if you want to high your score you can try again to get a better score. Even if the game isn't good on graphics but it has very complex scheme that you can do.
