Super cool!
It's quite hard too, which adds to the enjoyment. Would be cool to be able to play in the browser if you could export to HTML5!
I am very happy that you enjoyed it!
I am not sure if it is possible to have HTML5 and also a downloadable at the same time. If it'll be possible, I'll do both, if not then I am not sure which is generally more approachable for other people to play (i heard that people often have problems on certain browsers with HTML5), so most probably would stick with downloadable for now.
