Hey, thanks for the comment! A couple of the things I do regret not adding is stuff making enemies less annoying on your first playthrough and Patchouli not moving out of a group of enemies when she is being damaged. The memorization and resource management required to beat the game are very much intentional, and are main points of this game, so I'm glad someone recognized it!
The field doesn't increase in size, the screen actually zooms in and the player gets slower and I'm glad that a lot of Patchouli's dialogue works, as it was the one thing I didn't test and was scrambled together before the deadline.
Finally, I'm curious, did you end up beating the game?
