Well... Yes and no.
As it surely is about choices, if you go the full DIK route, it definitely is a porngame. As you will end up fucking everything, that's not out of your sight by the count of 3.
On the other hand, I agree. If you take you choices wise, it is a beautiful story about a boy becoming an adult and finding his way.
I did it all *laughing*
Fucked around like a rabbit, tried Only routes. I have a savegame for every situation possible so far. No matter what Cake does in the future, so far I have it covered.
Haha, yeah I know. I tried it once and reloaded for safety xD
Honestly? I could watch it the whole day. So satisfying... <3
