Fans of survival games will find Obby Only Up Challenge to be very interesting. This game consists of both moveable transparent blocks and perilous red blocks that must be carefully avoided. Don't forget the timer. It will push you to move faster, and the checkpoints will keep you from having to start over. The goal of the game is to get to the finish line by getting past barriers. The most important thing to do is to stay away from the red blocks, which can kill you. There are also places to stop and check. Try not to miss them and jump on them so that you can go back to the checkpoint closest to where you fell if you fall or hit a red block. Enjoy it!
