I really enjoyed the different magic systems and how the writing gave little hints as to how this world works. Your writing has a light touch that made the mysteries really fun.
One suggestion: on itch there is a setting to allow the game to go full screen. A Thunderous Trial does not have this set so it is stuck in a small sub-frame which makes the game a little inconvenient to play. It still works but it would be better if your players could use their entire displays to read your wonderful text.
