Hi, I have a endless arcade game on itch. So, in the metadata, it asks the time to complete a session (complete and level, run). But, as mine is a endless game, it does not have a playing session as you can play it as long as you want and it depends upon the player, I have currently set it as "a few seconds". But, I think there should be an option for and "endless"
Thanks for reading and have a nice day <3
