Thanks for the nice words and the feedback. I'm happy to get your input and it's great to hear that you're loving it :D
Deck Builder hover
I actually thought about that too. I started redoing the tooltip for followers on the board so you can see the actual card, and did some research on other card games and experimented a bit, and turns out it is a lot more useful if the card does not cover the cursor area but rather appears to the side. So I added that and voila - massive improvement. I'm probably going to straight up add that to all the card tooltips.
Deck Builder remove / add
Yeah. I've noticed this isn't ideal. It's something I can clearly see whenever someone is streaming the game. I'll have to see what I can do to improve this.
Difficulty & Resources
As Inxie mentioned - this is really player dependent. I think the game needs a better difficulty curve in general - easier in the beginning and a good ramp up. At the moment the enemies just aren't balanced as well as I'd like. And the resources are another thing. I want the game to be hard, so there will always be a degree of randomness to your food stores but the general economy needs some work..
There is also the idea - which is on the "nice to have" list - to add a selectable difficulty. That would probably influence enemy strength and resource gain to be somewhat acceptable to balance.
Enter Combat Crash
I really need to look at this. The key issue with bugs like that is reproducing them. As soon as I can create it on my machine I can look at what's broken. Alternatively a log file is always helpful, so if you run into the issue again, please do report a bug with the log file. Note that you'll have to do that immediately after closing the game. Opening it again will overwrite the log file.
The quick answer: Tablets are very very likely but will take a while. Phones are not going to happen unless this thing blows up so massively that it's worth to invest the time and energy to completely redo the interface to work on a smaller screen.
Also here's a quick Twitter thread on the topic: https://twitter.com/mnerurkar/status/921810718114148354
