The puzzles are fun and different! I enjoy the spooky/horror theme of the game! only thing I would change would be the frequency of ads. Even with them being 3/5 seconds long, it's a bit frustrating when there is one after you open the puzzle, immediately after the puzzle and depending on how long a puzzle takes, one or two pop up during the puzzle.

ads every 60 seconds, You can't get through certain levels without getting buffs with ads, then when you've wasted your time watching the ad for the buff, the damn thing doesn't even work! I used the 60 second buff to add time and it didn't even change the time. as for the game, some of the things you have to do have no correlation to the puzzle at all, yet you can't move on if you don't do it. one of the puzzles needed me to help a girl breath under water and the thing I had to use was a PLANT!

There seems to be a bug in the game. I can't proceed to any level past level 33. I've completed level 33, but every time I try going to the next level, the game infinitely lags on the loading screen for level 34. And then when I try to watch a video to jump right into 35, the video never actually plays and the screen goes blank while the background music for the game continues to play. Please troubleshoot this issue.
