I think the lava should rise only when you move- like when you move one or two squares, the lava rises a square, almost like a turn-based game. That way you can plan out your moves better. Otherwise, you're slapping down cards at the speed of light with little to no strategy. You can't even look at the dashboard with all its information because you gotta put down cards so fast. If you did make it turn-based, you could look at the dash before putting down a card and know what you need to know.
There is so, so much potential here, but the lava runnin' at you at godspeed just ruins it. Keep working on improving this, maybe there can be separate modes for different lava behavior.
