Bug Run

From BoardGameGeek:

You play as a caterpillar, a beetle... imprisoned for rebellion by cute but mean animals. To escape, cross the four levels of the dungeon to the roof. Each turn, buy equipment at the shop, take on challenges in specific rooms and cells, and launch into battle against increasingly powerful animals: the dungeon guards! You can be alone or joined by other players. Together, you will hope that your dice rolls will allow you to hit the bad guys, to recover the loot. But you can also let your "companions" fight, arrive just at the end... and pocket the loot! Only the strongest and most opportunistic will escape with honors! -description from the publisher
