Thing is that I was playing with SMS last weeks, and I did a test game using Allegro... Allegro.js actually. Compilation was done by the SMS command line compiler. Didn't test it on IDE,
I had to write a brief wrapper unit, and it works seamlessly. I plan to release it once it wraps the whole library, with examples and docs. Give me some time.
Here you have the test. On mobile and tablet devices it doesn't work as expected.
