Ez az első Phaser 3 játékom / projektem, és még mindig nagyon új vagyok Javascript, így biztos vagyok benne, hogy sok mindent jobban tudnék csinálni. Az első számú dolog, amelyet javítani szeretnék a kódommal kapcsolatban, az a teljesítmény. Ezután a kód hatékonysága és olvashatósága, de a teljesítmény a legfontosabb.

Visszajelzése akkor is értékes, ha nincs semmilyen tapasztalata a PhaserJS-ről , mert sok minden, amit valószínűleg jobban tudnék csinálni, csak a tiszta Javascripthez kapcsolódik.

A JS kódom:
