The game is very bare bones. I didn't see a lot of variety and I don't know if the cards can combo off each other because they don't have descriptions. I kept getting cum shot and I have no idea what it does. I assume one of the cards does something with it, but I just ignored it and loaded up with touch and bite and beat the first boss no problem. I didn't want to but those were the card I kept seeing. I went to three shops and I just have to assume there are very few card in the game. The three events I saw were all bars I got two martinis so I am assuming there are not a ton of those either. The game is fine. A solid four out of ten. I would rate it lower, but I did really enjoy the art and the story. It is just a bit shallow. I know it is not complete so I can forgive that. Good luck.
Thanks for your feedbeck,
All the cards have descriptions, you can find them all in the card inventory. There is an issue where the description isn't displayed during the actual battle, which can be a bit confusing if the player doesn't immediately realize the info is in a separate tab. That feature is coming in the very next update: when you select a card, it will pop up, and the full description will expand.
As for the cards that supposedly don't work together you're not entirely right there. Even now, you can put together several different builds and tactics.
You're right about the events, right now there's only the "Bar" event. I actually have three other events ready for the next update; they just needed a bit more polish than I initially expected.
