UI doesn't scale on 4K monitors
in Bug Reports
I'm trying to play on a 4K monitor. Windows is running at 200% scale but the in-game UI appears at the native resolution (which is unreadably small).

This is a known issue - thank you.
It's still on our list of things we'd like to add to the game. Until then, take a look at my reply on this post which explains how to enable the (mostly) functional experimental version of UI scaling; http://forums.castlestory.net/discussion/comment/4248/#Comment_4248
Since this isn't a fully supported feature, there are some issues such as this.
You'll want to save and reload your current game. You might have to close Castle Story and launch it again if that doesn't work.
Sorry for the inconvenience.
