2. CHALLENGE try making an "invisible portal". This is like a hidden portal that is a bonus for the player to find.

3. CHALLENGE if you can find the invisible portal, make it visible once found.

4. Find a cool, possibly animated sprite or appearance for your "portal".

5. Vertical portals... very difficult!
