@FinalHero2, there already is a special thing that gives heroes when they get to level 1000 , like what itsme0 said. When you reach level 200, the hero's DPS would be multiplied by 4, and 4 again every 25 levels, when it reaches 1000, it would be multiplied by 10.
@TigerTaylor123, that can be made by regular players using modules, I don't know how to make them though, maybe they could be in the forums. http://atelier801.com/forums
@PetSilver, there's already a skill tree that both deletes a single object (Mechanician), deletes everything you built (Wildling), and deletes nails (Physicist).
Just like the game "Outernauts", they removed the energy system, and by that time, the game was nearly PERFECT! Unfortunately, the developers decided to close the game and make it mobile instead. 10/10
Edit : Right click the game, go to settings, right click on the game again, but not on the thing that pops up, go to quality, and click whichever quality you want.
Sad, I remember months ago when tons of players play this game, It was awesome to play with over 50+ other people in the tournament... But now, almost no games occur, and i'm the only person in the Dillo Hills 2 chat room.
