Glad you enjoyed the game.
Good idea, I can change pressing OK to type the whole message first instead of skipping it.
Regarding the jitter: It's funny, I did notice a while ago that the movement seemed "off" but I couldn't put my finger on it and I was thinking I had gone crazy so I just ignored it lol. And now 2 people this DD have noticed it! Looked into a bit and I see other people complaining about this with Nez (the framework I'm using) I hope I don't have to write a custom Camera class...
Damn I thought I found all the "string not found" messages but you caught one! (I'm refactoring the game so all the strings come from external files instead of the code. If it doesn't find it, it prints that message)
Adding a heal before the first dungeon is a good idea.
