Cool, thanks!
While I have a moment I thought I'd respond to your other suggestions and questions:
Salt Miner's cap poison affected by Tilo's mask - Done!
Candle hat affecting enemies - Good idea! I'll discuss it with Seith, there might be something in that.
Skappbeetle egg clue - Rolo will give you a hint about the Skappbeetle egg locations if you talk to him (and later reveal the locations on a map), but Silas is a good candidate for giving a hint also. I'll see if I can do that.
Faustus - He's going to be a lot more important, and perform a role similar to the one you suggest.
Hornet nests - The hornets' nest will play a much bigger role in the final game. I like the idea of knocking them out of trees, though!
Stealing a flat helmet from a guard - Yes! If that's not working then it might be a bug.
Horses - There are no horses in Dwindling Height, no! (I wonder what noise you're hearing)
Pickable locks - The type of lock on the container should indicate what kind of locks can be picked. You don't have to be wearing Tulong's costume to use the skill. This will mechanic will be used more extensively in the future.
Costume animations - Nice idea, I'll pass it on to Seith.
Function of the lute - Yes, the lute will play a much bigger role in the final game, and Tilo's performances will also be more elaborate.
Bell jingling - This is something we're currently considering.
Guard AI - Seith's implementing a lot of new features to address some of these issues with the guards, more details in the near(ish) future!
Carrying a light source and tool - The candle hat is the main solution to this issue, but we're also discussing some other possibilities for the situations you describe.
Uses of the day/night cycle - Definitely! We have a lot of other ideas for changing up the gameplay challenges at night, some related to other questions you've asked in your post
Thanks again,
FN
