I have one more note on TheMaze challange. The map is random. I can reload the same AI several times on the same maze. But I cannot change AI. To change AI I had to EndMatch and select TheMaze again and select different AI from the list but because TheMaze is generated by random,I will run new AI on different map, so I cannot directly compare what AI is better. I would like to see a button like "select AI". Or EndMatch will not navigate me to the main menu but just return one level back, so I can select AI from the list and run the same TheMaze again.

Generally, I don't like that EndMatch button sends me to the main (root) menu and I would prefer to return just one level back.
