That would be fantastic!
Yeah I think that would be a huge help! Especially for the first couple of battles having no healing glyphs can be brutal. Now that I've played him a bit more I think the main things I can suggest that would buff him nicely would be what you mentioned, fixing the thorns buff for sure would be a huge help, giving him more defensive abilities would be good, since he can easily get horrifically overpowered by later-stage enemies like the soultaker and the hunter, and for the more aggressive builds giving him more options for things that pierce thorns without him getting hurt. One of the things that makes the kitsune so strong is their ability to draw so easily with the flash cards, maybe giving him a couple flash cards with different effects could be helpful.
Edit: I made this comment before reading the update notes for the full update so some of my goblin feedback there may no longer be applicable, please take with a grain of salt.
Ooo that's awesome! I'll definitely check the new update out asap!
Are there any particular run details you want me to send you a screenshot of?
