Nice game, pretty clear that it's doing well, so rather than talk about all the things it is doing good I'll focus on a few things I think could improve this gem...
I'm playing in Chrome Browser
Bug/Odd Behavior:
Sometimes I can not interact with the Deck and/or Settings Icons
When in the shop this seems to happen specifically with the Deck, even when I can interact with these icons during the run, but sometimes I just can’t interact with either of them at all.
Information/Clarity:
An indicator of the Ore I will gain from a card would be nice, similar to how the Scorium gain is showed in white/grey on the meter before actually playing the card, maybe a ghosted number under your Ore count in the area where the number will pop up once you actually play the card? This is particularly helpful for learning the system, when I'm wondering if a conditional effect on a card will activate under the current conditions a hover over tells me before I lose a run over not knowing how to interpret the language.
Language Clarification:
Mineshaft/Minecart Cards: If there are already 2 or more actions in play.
Some cards read: “If the last card played this turn was an action…” this led me to believe that it would trigger on the final card played on that round. I think “If the previous card played was” or “If the most recently played card was” would more clearly indicate the intent.
