Pour le moment c'est du grand grand potentiel, je suis étonner de ce qu'on peut faire, mais de gros freeze, avec et sans shaders, et il manque encore pas de fonctionnalités qu'on aurait aimé voir, comme un guide des erreurs java... des crash sans erreur via la console, ou des guides pour changer les touches directement dans l'application. Mais en tout cas grand potentiel, hâte de voir son avancé.

J'utilise ce launcher tout les jour sur un ordinateur portable avec peut de performance et pourtant je peut lancer le jeu et avoir le launcher en arrière plans ! Note de 5 pour ce jeu fluide et la vitesse de démarrage extrêmement rapide comparer a tout autre launcher (launcher et jeu ce lance très vite). Je le conseille ;)
