I like that everything was a high stress environment since it helped each puzzle fit the theme of taking a breath. The games in each level were fun and the puzzles were well designed. And the art direction!!! Good lord this looks beautiful!
There was no through line connecting each level. I suggest setting up a narrative to make it not just a random assortment of time sensitive puzzles and instead a group of connected puzzles that needed to be solved in order to achieve a greater goal. Also, surgery is more high stakes than archery, so the order of levels seemed off. Surgery should be the final level. Something as simple as the player character is student in a elite private school that trains kids to be doctors and today is their big test. The maze is them getting to their class. Not sure how to work in archery, but you get the idea.
There also isn't much of a through line for the theme. If the game is about perspirations and staying calm, then include that shaking feature in the maze level in every level of the game to show that player characters nerves.
Also, the levels took a long time to progress, specifically level 1. Maybe consider lowering the time between start of the game and when the book comes up.
Overall great looking game and the mini games were both challenging yet beatable. Well done!!!
