Oh thats not good..
Do the Traps heal you in the other dungeons too? Is it just Attack Cards that sometimes heal? Do you heal the amount shown on the card?
Okay I'll be able to look into this and fix the bugs in the next few hours (might take a bit longer depending how tough the bugs are to fix)
Thanks for letting me know though! And I'll keep you posted for when I update the files
If you die again, please let me know if you get stuck in a battle/island screen again, cheers
