Love it! I spent too much time playing it last 2 days :D
Would love a random deck each time you play - maybe keep the current mode as daily challenge (make a score screen with a date so we can compare top scores?). This is because the "same deck for a whole day" makes me optimize my runs (more of a strategy), while a completely new deck makes make decisions on the spot (more tactical play). I think having both in game would be awesome.
Also - I would gladly pay for an android version!
