Thank you so much for recommendation, I'll try something out, probably just put timer and on timeout it sapwns player instead of immediately in _ready() function
I just tried it but since it spawns enemies at the start and shop at the end of level and also two portals, doesn't really work that good, even for enemies it still lags with timer, but yeah at least it's only on first level and only on web, still thank you so much for suggestion.
Also i really like your blackjack game, animations and sound effect and main menu, everythings is so interesting, looks like you had fun with all those little things, good luck in game jam
