Late to responding, but thank you for playing my entry (Same to everyone else who has)! And for the kind words. I appreciate it. :)
As for the whole revival thing, there's both an item for it and a place to revive party members in The Depths. You gain the ability to buy the revival item once you hit Lv. 3 or so. Two of the 6 possible floors have one you can find in a chest hidden away.
Out of curiosity, which floor with the jumping puzzle did you have? Three of them have one (I almost always end up making a jumping puzzle like this. Lol).
