I like the subject, but the current discussion seems a bit off topic. To be back on topic, I share with you the best trick to learn:
- beat a level (should not be a problem on the lowest difficulty)
- go back to the map
- click on the level name
- click in the “difficulty” section
- select a replay and watch!
You will see the submitted code, and you can even change it and run it as if you were the person who submitted it (including hero, items, etc).
Note:
- some levels’ “all time” leaderboard has bogus entries which will not load – in this case select the “this week” or the “damage dealt” board
- this works for all levels!
Here is a an example replay:
Later, you may also want to learn about fleeing (warning: advanced trickery!) for example in this topic
Also, using the non-free heroes gives much more possibilities to fight (ranged weapons, spells, etc).
Cheers
