Both observations are correct.
-Using unlock all characters can cause you to lose all characters actually. I wouldn't recommend using this for now.
-raid levels option start to get glitchy around 16 and up. It won't level up at all once you read 20 (using the trainer that is. You can still level up normally).
invincible/no hit detection please. this would make earning the "no damage" award easier.
Thanks for the trainer. For a first release it is very good and hits on nearly all points.
