Whenever I see a game that uses the arrow keys and doesn't offer WASD as well, I can't help but see a game written by a non-gamer. I consider these fundamentals, and a shibboleth of whether I should care.
Literally 95% of 2D games on a PC were controlled via arrow keys. Not many allowed rebinding. Even in emulators, until later on.
You sure you're a gamer? I've been at it since about 1986.

While I'm not defending a slop port, I have to question your gamer credentials. Maybe by gamer you mean a Call of Duty player? WASD is traditional for FPS/TPS games that expect you to have one hand on the mouse. Most 2D games, and every emulator I've ever used, have never offered WASD.
