September 4th Progress Update
Added 2018-09-04 09:24:02 +0000 UTCI was working on the 7th and 8th Caverns bosses and noticed the 6th level boss needed a few tweaks. While I haven't actually tested any of them, they should all be good to go. I do still need to add common enemies for levels 7 & 8 before The Caverns are 100% completed.
Also, here's the 4 character concepts that Mavis drew last night. It could possibly contain spoilers, but lacks context.
