I will also do the same. Only JS Canvas Api.
Best of Luck :)
I only played on android. The concept is very cool. The only thing is difficult on android is that the botton position is not fixed like jump botton on right and movement bottons on left, etc like this, So sometime my fingers got tangled馃槄(hope you understand my english) and I am anable to press right button on right time.
The game is PRETTY COOL
