The comments about the ad is true. It is a little much, but you still shouldn't let that take away from the game. I found it both pleasant and enjoyable. A+ for me I had a fun time playing, and it wasn't too long. A well rounded game, good job!
I'm not sure if anyone else feels this way, but seriously I've spent like 8 hours just spinning that stupid slot machine and haven't hit the Octo Jackpot yet. This is really annoying. Why put a quest in a game that you have no control over, and is 100% based on luck. I'm not sure how that is in any way suppose to be fun or amusing. It's kind of a turn off for the game which makes me not want to play it at all. Putting these kinds of quest or achievements in a game in my opinion is just silly.
