clear benefits are actually a real neat thing i must say, and it's really lovely to see this type of a game.
(btw: if you clear wave 1, you have to reload XD)
what is the point of prestige right now? you should just have left prestige out for now, but this game has really good potensia
things that should be
debuffed: devoutness (click bonus upgrade)
buffed: starting stuff gold income in late game; the building cost adding whit every build building (btw: if not english or never heard this type of stuff in buffed/debuffed area, this basically means it should be lowered cause it is in the buff area, this is becouse buff's and debuff's are looked from the player's point of view) upgrade cost for lower tier upgrade's minus devoutness.
if you are having bad time knowing what to do whit the prestige, you should play endless training, it might look basic at start. but it nailed the prestige stuff. (i am NOT here to advertise endless training, but it is really good game and it shows game doesn't good graphics to be good)
