Way too slow even for a pure idle game. .02 upgrade per level? At level 20 for cash only pulling $1.75 every 4 second run when it costs almost $8 to level up? And it's pure idle so no clicking to speed things up at the beginning which makes it seem even slower. Feels more like a waste of time than anything amusing to play.
Meh. Not that scary, though the seek and find for items is a pain in the ass with a dim monitor. Having to click on the key and unlock the door every single time you want to enter a formerly locked room is annoying as well. If the torch can be used automatically, so should keys.
