hi @Treeman92 any luck with your finding so far?
I’m having the same problem setting up Phaser 3 for Ionic 4/5 too. I’ve been searching for few days now, and found no clue about how to proceed.
I tried both compile-time & runtime integration (same as your solution), but I couldn’t get any far and I also have the same “this.game.load is not a function” problem.
Please advise.
