Thanks for playing! Yes, I made a couple too many "tutorial" levels leaving basically only the last level posing any real threats.
If you don't mind me asking, when you say there isn't any push to move forward, do you mean like, 'there isn't anything stopping you from just chilling with attack cards until the enemy walks up to you'? or more of a 'there isn't much motivation to make it to the next floor'?
Thank you so much for the feedback!
