Pretty much exactly as the title says; it's 'really' cool that there are now 9 leaders to choose from at the start of a run and it's true that human working memory has a capacity of ~7 chunks of information but when you have to compare Health, Attack and potentially a unique Ability for each leader, it's all a bit much for me to take in at once.
I currently screencap each set of leaders and paste them in Paint to compare them directly (like in the picture) but it would be cool if there was a button you could press to see all 9 options on a single screen for easier comparison.
