I think you need to either nerf the cost scaling of stone or increase the stone multipliers...even when playing to the very last tile built up - you are just sitting around waiting on stone. I had over 107k wood, 7.4k magic, and 15k tech but still had to wait on stone. It takes from the enjoyment of the game. Also I noticed stone problems not just in the end but often I was waiting on just stone.
glitched pile of trash ruined my game =( the rating tanked and visitors were angry and leaving plus no matter what I did- upgrading janitor or buying new ones it wouldn't go away. I even tried demolishing the building it was in and rebuilding.
I got frustrated I couldn't use the needle on the sewing machine to then sew up the bag so finally looked it up and was: "duh...you can do it without the machine stupid." Later when I went to the second floor I panicked when I dropped the screwdriver thinking it had fallen into the elevator and spastically clicked until my first death...second death was when I tried to go back up and tie her up with the rope to search the room...bad idea...
In a game where millaseconds can mean the difference, I suggest you offer a variable effects/graphics setting so I can turn off the extra tail on the moving square and blinking background colors because the game will "freeze" momentarily trying to render, and it makes the final few levels ridiculous.
missed the very first chest. the one in the sword chamber by accident and can never get it to complete the bloodless ending because of the meteor thingy the watcher threw...after all that time spent getting all the other pieces...fml
turned off everything (including instructions after the first time) and when got to the final stage with only the 4000, and 6000 left was like "this is impossible" then realized...never used the rockets...everything would have been so much easier...
*SPOILER* you end up going back down there
