I have a question. Is it possible to give 100% discount on your newly published game on itch.io?

Actually I wanted to release my game for $1 or $1.5 and I wanted to give it for free for a week or so to get reviews from gamers if my game will be worth their money or not.

Or should I just release it for free? And make it paid later on, is that possible?

Not sure about the 100% discount, but yes you can change if the game is free or paid anytime you like.

Yes it's possible, you can change the price at any time. But I'm not sure if people who already downloaded the game for free retain access to it once there's a minimum price.

I would've made a demo version but my game itself is probably 10-15 minutes long.

I think I should contact itch.io.

EDIT: Would it really be a good move to make my game paid? Considering the number of downloads a game gets here.

I know that depends on the quality of the game and marketing, but you guys would probably know better.

If you make your game free now, then later add a price. The people who downloaded the game while it was free will not own it, so they will lose the ability to download it.

If you make the game paid now, but then create a 100% off sale, then the people who claim it will forever own it, regardless of what you set the price to in the future.

You should choose what you think makes the most sense for the kind of game you're making.
