evilpwner: When you reach the room that says: congratz, proceed to the next room to claim your prize bla bla, don't head towards the door. Run backwards and you will fall through the floor and find the secret door.
It gets boring after you get a forcefield... Otherwise, it was fun seeing all the forms my bubble tank could take on them letting it die and de-evolve. Although the game was somewhat limited, it was fun to play and worth my time. 4/5
