added mouse/touch controls and a "game over" indicator to cat cubes today. it's not active in the new build, but i've also started working on adding a menu to the beginning for options (and now it will take even longer since it needs to support touch controls too, oops!) also was able to set up an emscripten-uxn web page with it, and it works well on my phone with the touch controls but i might need to make a portrait-mode version so that it fits on the screen better.
