I don't know if this would be the right (sub) forum to post but I think this more of a demo then a working project at this point. Actually its more of a test. I started looking for a Java 2D engine recently and come across Slick 2D. Following some of the tutorials and some forum browsing I now have a simple demo with Tiled (tmx) level and polygon intersect collisions. All using Game states and Entity/Component code.
Currently I am looping almost everything each update for collision and movement and was wondering how the current code would hold up/scale with more objects. Thus the Goomba spawner come along http://www.youtube.com/watch?v=cHWlXJalNBI
