D'un autre côté, ils sont que 4 dans l'équipe de développement, donc il leur faut un peu de temps.
Comme ils l'expliquent dans leur forum :
It's PSN download only at the moment - We're a very small team and entirely self-published, which means we pay for everything ourselves (testing, translation, that kind of thing). Bringing out a physical console copy just wasn't doable for us without publisher backing, and that comes with a certain amount of baggage.
Of course, that's not to say you won't EVER see a physical copy, it's just that PSN is our focus right now. We'd also consider releasing versions for other platforms, if the demand was there.
