Upon playing this more polished version, I have to say that I don't have that many complaints. It does feel a bit RNG-y that you can just get screwed and not get any Candle cards at the beginning, but there's definitely some interesting strategy if you realize that there's only one copy of each card in the deck, so you can prioritize keeping the cards based on what you've already discarded, and how the different weak-spots are organized on the cards.
Only complaint is that there isn't any sort of "you win" sort of message, but it is an arcade-style game, so I get that. Also, unless I'm missing something, there isn't a way to play with that gray succubus girl? Although, I assume that's probably planned for a future update. If so, I definitely look forward to it!
