First thing that I felt in love was the splash screen. It is done so good! Next thing I enjoyed was the options menu but I'll be honest, I got a little bit lost with "Back" button on credits screen. Maybe add more highlight/color to it to increase visibility ? The animation was super in place. The atmosphere, music and sfx are all very well put together. The idea is also interesting. To put it shortly, game executed professionally.
Things that I didn't really like or think could be changed/improved:
* Tutorial text placement. I am looking at the mid/bottom screen as its where the cards and "my hand" is and had to constantly look at top of the viewport for the text. Additionally the text merges with everything else. Maybe additional highlight or a separate container would improve it.
* The shadow icons on the cards blend with the number too much. Initially I had a strong feeling its "10" shadows (bottom right) but its 1 (shadow icon). Would want them to be more distinguished so I can clearly see what is an icon and what is a number
* Nice to have: When choosing a path maybe highlight the "path"/"door" when hovered for cleaner UI/UX ?
* When chest opens maybe its better to remove extra click for next item ? all items could appear and on hover you could show what it is.
