Casual Quest

add a link to the class list into that "More Info" section of the hub

create a player listing that can be brought up much like the chat box, showing all who are connected, and their status (idle/spectating/playing), and their icon if they are playing

add a little special effect or animation when an enemy dies

when at the main menu screen, if a game is in progress, show how many players are currently playing and what wave they're on

if it wouldn't be much effort, make the chat box look similar to the main game's pretty, square interface instead of using the default

consider allowing games to be started at several different possible waves (such as 1/30/60), altering what tier of class you randomly start as (0/1/2 or 0/1/1). as it stands, i don't even know how to start at wave 60 instead of 1. another possible way to work this feature: once you've passed a certain wave landmark(30, 60, 90, 120) in a game where you fully participated in the past 30 waves, you unlock that landmark so you can always start a new game from that point. that way everyone can quickly jump in and start playing at the difficulty appropriate to them, instead of first grinding out 100 easy waves they've done many times before
