Another Update! Now landing is possible!
I wrote about it in my development blog. There you can see a longer version of that gif and read how landing is implemented: tmblr.co/ZXktVf2HKn_3c
Next, I am working on the sound! I have the self-imposed objective to make the game take the less amount of disk space possible (Ideally, less than 1.44 mega bytes, the size of a floppy disk), so I wont be using pre-recorded sound effects at all. Instead, I am working on some algorithms that procedurally generate the different sounds.
