I jumped on for a quick game last night and found someone waiting to play so joined them.

For me:
-The guy was a much higher level than me. I sort of felt like i was cheating because he carried me through the third boss which i was slowly grinding my way towards. For me i personally don't like to cheese stuff like that (as a big part of the game is progression) so i ended up leaving the game. Would be nice if there was an option to have your coop or solo progression seperated perhaps. I know that might not be popular. I'll stay away from coop now until i have beaten the game solo just because i want to do the work myself the first time.

-Between rounds needs a timer. When we were picking cards it felt like a timer was needed when you play coop so that you aren't stuck waiting forever.

-Pausing or checking stats seems to pause the game for everyone? Would be nice if during mutliplayer the game kept running in the background. I felt like i was disrupting the other players game by having it pause while i checked out stats.
