I'm sorry to hear you experienced that bug. I'll upload the fix as soon as I'm aware that bug fixes are allowed after the submission deadline!
I definitely agree that the early game depends somewhat heavily on viable early cards, and am currently working through different solutions on how to rebalance the difficulty curve, and make the card drafts feel more fair.
Thanks so much for playing, and for the feedback!

Have you played inscryption yet? In that game you can make a card when you 'die' which is a combination of some of the cards in your deck randomly chosen, for each of the variables (health, rune, cost) and then that card gets put into the game for the next playthrough, you may or may not get a chance to pick it up, but the idea is you want to pick up super powerful cards knowing the next time you die there's a chance you can use that card to make your death card and then get the chance to pick up earlier in the game giving you a nice high value card for your deck if the rng falls in your favor.
