Tämä on ensimmäinen Phaser 3 -pelini / -projektini ja olen edelleen melko uusi Javascript, joten olen varma, että monia asioita voisin tehdä paremmin. Numero 1, jota haluaisin parantaa koodissani, on suorituskyky. Sitten koodin tehokkuus ja luettavuus, mutta suorituskyky on etusijalla.

Palautteesi on arvokasta, vaikka sinulla ei ole kokemusta minkäänlaisesta PhaserJS: stä , koska monet asiat, jotka voisin todennäköisesti tehdä paremmin, liittyvät vain puhtaaseen Javascriptiin.

Oma JS-koodi:
