We rather liked Paper Mario: Color Splash in our review, and now plenty of Wii U owners around the world have been trying it out for themselves. Naturally different play styles put its mechanics to the test, and an odd developer oversight (which should have really been found in QA testing) has emerged.
As posted by 'Fatguy703' on YouTube, if you somehow load up your card collection with nothing but hammers and encounter a flying enemy, the game doesn't let you retreat. As you can see below, they had to spend a long time using up all of their cards before the 'flee' option became available; it's a rather farcical situation.
We doubt too many players will easily recreate these same conditions, but it's quirky nevertheless. Hopefully this is the sort of issue that can be easily addressed in a small patch.
With thanks to SLIGEACH_EIRE for the heads up.
