don't forget this isn't clasic idile clicker.
they added most annoying system... hero death which is random.(it's random hero selection, random time of death, yes your hero can die when boss still have 90s left in timer)
and only way i found to avoid hero deaht was active play(click every second) or kill it in 2s of spawn.
why is it a problem... if you don't have luck your highest tier hero will die, because is random and now you can wait 12h(to continue or to get full reward), use gems, or take half crystal reward and restart.

and it doesn't work as idle clicker since time between upgrades is to short and there is no point in farming same stage.
fap titans would be good idle game from mehanic point of view, but all premium crap and how hard is to get anything in game, made it into worst idle clicker.

Realm Grinder was good idle game sometimer i let it run for days before getting new upgrade and there was point in reset and reincarnation
