Thanks so much for the feedback!!
Totally agree - not having a quit button on the title screen (or even just Escape closing the game on the title screen) was an oversight on our part. Will definitely have one in the fixed build.
Also great note on the subtitles - our two voice actors ad libbed a bit at recording time (a few hours before the deadline) and we didn't get the time to go back and fix the text, but we will also update it to be accurate :D
During planning we had ideas for two more elements: wind, which would be more effective at movement but less effective in combat, and stone, which would be the reverse. We didn't get the time to implement them and we worried they may have been a bit confusing. Environmental hazards you have to use elemental cards to move through would be a great idea!
Lots of different places we could take this concept - I'm glad you enjoyed!
