Oh, I think this is the first or second time you're hearing about this engine. Someone had suggested a game engine with the same name to me before—maybe that was you.
But bro, if you use the Cocos Creator game engine, then in my situation you won’t be able to use Player2’s NPC AI system. As far as I know, it’s only available for Unity and Godot right now, and in the future it might come to Unreal only.
Your game is generally pretty good, but the attacks just keep missing the monsters, and the monsters deal a lot of damage, making it quite difficult. It's also hard to dodge many attacks, and then there are the flying bat monsters, which makes it even worse.
