Am I missing something or am I stuck here? 
I really really like the ideas in this. There are items that make each run different, you have skills that you can use and actions you can take without losing your turn. I love all of that and they are implemented beautifully here.
While the game starts out with a big, scary block of text, I wish it also explained what each level of skill actually does and what each type of tile does. I think the star is a damage over time?, Heart is healing, crosshair is charge and bullet is damage. I have no idea what the trophy is though and that makes it hard to play around them.
I got to the last boss twice but I couldn’t beat it. I intend to try again though.
