I agree with the lessons. The tag game has a design problem, though: if the players are any good or the computer has good AI, the only characters that are able to catch the other players are the red one and the pink one. Because everybody has the same speed, so the "safe area" won´t help you, nor the teleportation. To correct this, the one on the offensive should be a little faster than the other ones (so that their powers should be used primarily for strategical defense). That, or the scenery has to have more complex means of interaction. Thank you for enduring this. Good luck on your works.
