I loved it. Found a minor glitch, when distracting the guard with the phone, if you interact with the phone again the scene repeats and the guard moves another tile to the right of the phone. Other than that, I loved the difficulty increase and the need to use strategy.
The betting part is a bit easy to exploit though, if you save, bet as much as you can, save again if you win and reload if you lose, it's easy to have a easy infinite supply of money. I went in the back mission with tons of items and an attack buff from the vending machine.
Small suggestion: Instead of one use per mission, I think the vending machine should be one use per person per mission. For example I could buff Rory's speed and Hex's health for 10k each.
I really liked this one. The questions and dodging fire areas weren't too easy but not overly hard, they strike a good balance. Plus the ending was pretty funny.
For those that aren't getting the achievement, in one level you need to open a new window to flip the switch, shortly after that you will be disconnected from the Kong Server. Once you close the other window, look under where it tell you that you are disconnected, there should be a button to reconnect. Click it and carry on and you should get the achievement after beating the game, it worked for me after beating it several times. You can see if you are connected by looking at the plug over the side menu. If it's green, you are connected. If it's red than you are not connected. Refreshing the page may also reconnect you. I hope this helps.
Thanks :D
