Can't believe how complicated Adwords is

Google ad services are so complicated. With Admob I couldn’t delete some entries, a weird intentional “missing feature”. Ok it was my fault. But is it also my fault in Adwords, that I need to understand a gigantic interface for just starting some ad? It “seemingly” worked then, but now I’ve waited 10 hours to get a single impression, for $5! Game prices * convertion rate is so much below that, why didn’t I even get an impression? I would understand if I got impressions but no clicks, since my game artwork is really mediocre.

All I got was an install from UK, who has been 99% sure the guy who approved my ad, using android 4.2.
