itch.io

Never played this before and I know as a creative person, you don't want someone to skip something that you've made but you never know if they've installed this on the 10th computer or the 1st. It's probably a good feature considering many people might want to skip them the first time to see if they like the game. 

Ultimately, it's your game and you should do what you want. I'm just here checking out fighting games.
