Hello Hei'an, and ohh! You are actually meant to use David's healing for that part, so you can switch over to David to use up your FP :) But I'll take the possibility of getting stuck there into consideration and fix it for an update. Thank you! :D
Ok, got through it. I was playing on keyboard and didn't know you could switch by clicking on the other party member, so thanks for that. 'u'
Awesome! You can also use the arrow keys on your keyboard to switch party members! ^^ Hope you enjoy! :D
