I was not able to work on the port so much this week. This is still a gif of the rolling demo and this is not playable yet.
This is still pretty rough. I tried to add controls but now the game crashes in the simulator when I try to launch the proper game. I also have a new crash on device, a totally different one. It will be (not) fun to track them down.
At least the rendering is a bit better. I use a dithering map texture which indicate which part of the screen is blue noise, ordered of just threshold. On the long term the key will be to add contrast to make some element like enemies pop more.
But now I went back to the blue noise rabbit hole and started to experiment generating my own blue noise textures. That will be interesting to improve the picture quality (and I have an idea that might force me to go back to my video experiments)
