I'm not sure if there's a way to end the game and I'm not sure how the original template is compared to this, but I think it's a good way to start your journey developing in gdevelop if you're not familiar!
You got it right, I'm new, practically the first time using Gdevelop, but I've always been passionate about creating games, I'm only good at Construct but I admit that Gdevelop is a good cover that delivers what it really promises, I loved it but I have to study this engine more, I hope to at least make it into the top 5... Thanks for commenting and good luck too
