Aw thank you so much! Really glad to hear you're enjoying it and thanks for giving feedback
That fight in particular however is actually 100% beatable.
SPOILERS for anyone who wants to come at this completely blind,
but Furret's catch rate is the same as Makuhita's is in the original game, which is 100%. You can catch the Furret and then the enemy can do literally nothing to you, being a normal type.
Hope you enjoy the rest of it and don't hesitate to give more feedback, it's really appreciated!
