@misiak:
It would be great if you could port Lincity-ng to GLES! I'm not sure if it's worth it from a performance point of view but it would be a nice learning experience to know if GLES is faster than pure SDL. So from an academic point of view it's definitely worth it.

Just for reference, I had a look at the source code myself some time ago and I wrote it down here [1] in the penultimate paragraph. But I guess you already know what I've written there.
