Hiya, it's a very interesting melange of the two games! I have a couple of issues, all of them related to resolution.
I play on a laptop, 1766x768, and the game drifts off the edges at 100%. Zooming makes some buttons unclickable, as their size and their location seem to be unrelated?
Having a tarot bubble in the middle of the screen, and no idea how to dismiss it, meant that after prestige my cards were tumbled on top of each other and I couldn't see any upgrade costs for each card slot.
Aside from this, I really look forward to being able to play the heck out of this!! Nice work :)
