can you reveal the price or is that still private until you want to release it on steam?
That will depend because steam allow to do localization pricing
So if you want to get an approx this is the way I will do the pricing for every country steam let me localize the price:
Minimun wage per month of your country × 0.004
And I will launch the game with 40% discount for 7 days so take the last number you get and multiply it by 0.6 and that will be the price at launch
