Enjoyed my time like the first chapter, but I do have some suggestions:
It took me a little while to understand that the "Z" above the cards was my action counter, even though this may have been in the first chapter. The Red/Gray action dichotomy was also something I'd read in the tutorial, but didn't come to fully understand until much later in the chapter. I'd suggest highlighting the red and gray sections of the counter and the cards during the tutorial to better connect the titles with the game elements they reference.
Secondly, if there was a way to check my deck and my cards' abilities, I couldn't find it. I would suggest adding this in, as some cards, like the fire shield, can be a little complex despite, and while you did explain the card when it was given, I'd easily forgotten all that information, and would have liked to have been able to reference the card again to refresh my memory.
I hope you found at least some of this criticism useful. Thank you for the fun game. I'll be looking forward to the next chapter.
