This one should be really good, it's based on prboom+ and seems much much better than Prboom4android.
Unfortunately it's 2$...
Anyway, I asked author to implement some COMPET-N feature for demo playback (I enjoy watching demos on my phone) hoping to see that implemented i'll buy it without a problem
If someone tried it, please tell us how does demo playback work?
