I feel its too simple try remaking it maybe with a more complex system for example an idle space ship game where u build parts assembl them in a puzzle-like format to create more power for shield weapons armour the possibilities r endless and it would appeal to more people so more people would play it
nice game next time you create an idle game do this thing again just please take the time to polish refine and extend and balance great developer please spend some more timeon the next idle game and make it multiplayer:) ;)
good luck
If you get to the last boss and use a pickaxe on the back wall then click the sorcerer he says " you think you are clever" and spawns a wall of infinte monsters
An idea for resets is make it so it gives 10% extra on top of the 2 times so i still need 400 billion but it is faster by 10% compared with 200billion etc
Can't say without spoiling it :)
