I’ve had so much fun recently playing this game. Despite its tiny build it really gives that same feel of a large MMO. I wanted to compile a list of things that would be cool to incorporate down the line. 

• Larger variety of monsters
• More final boss like monsters (dragon, spider queen, unicorn) - these were SUPER fun as I had to journey around to find help from other players just to take them on. 
• Variety to monster spawns with area not being super exclusive to just one or two types. It would also be great if there were monsters that gave larger xp rewards than usual. It would help the grind and be an incentive to hang around an area searching. 
• Voice Chat seems to be hit or miss with some people saying they can’t hear me or it sounds really quiet
• Integrating the crank would be cool if done right. Maybe some sort of charged up ult attack that does more damage?
• I really like secret passages and puzzles. I thought the secret room that takes you back to the library in the first area was super cool.

Just wanted to tack on how much fun I've had with this as well. Really interested to see how this develops

I think the first expansion definitely covers some of your points here! 

Voice chat has always worked better if you get right up on the mic. I tried a few methods to boost the volume/sensitivity, but it ended up blowing out the audio and making feedback.

As far as crank use goes, when I do end up using it it'll likely be for non-combat stuff. I guess it's a very personal preference, but I'm not a fan of games that require crank use along with dpad or a/b. I know PQ isn't exactly twitch gaming, but you do sometimes need to reposition/use targeting quite rapidly in some situations and throwing in some use of crank there just feels like it'd be uncomfortable to me.

How do we all feel about fishing?!

As far as secrets and puzzles go - i would LOVE to do more of that kind of stuff as well.
