The 20 Second Dungeon

As you, Jimmy, attempt to escape the horrifying dungeon and reach your escape in the form of a portal, a clock is slowly ticking down until your fatal demise! With this being said, you should also look out for the vicious, evil dinosaur roaming the dreary halls of the abandoned dungeon. Good luck, you'll need it.

P.S. This is the best I could do and I hope you like it
