I have under a day left of the cover jam #4. I'm finding it not easy to get the end of a jam with a presentable game yet. I still have lots of techniques to learn about games development - it's not just straight coding. But I am at least submitting something, which is known to be one of the challenges of jams. I took a decision to try to concentrate on 3D game development for now, in the hope of avoiding my much worse pixel pushing!
