Nice game. I'm glad you identified the major problem in many online blackjack toys - that they've got a scummy vibe to them - and done a clean break from that.

Some ideas:

* Keyboard shortcuts would be welcome - the click targets are grouped together on desktop and are not very large.

* Upscaling the game on desktop would be helpful for usability, it's quite small currently.

* I know it's just a hobby project, but it seems the action buttons are not in the tab order - was this deliberately removed? This seems like it would be a really easy step to take for at least minimal accessibility. Currently, a mouse is required on desktop due to this problem.
