Off to play yours then,
Played a few rounds of your game against my brother, and It has an interesting concept, but I'm not entirely sure what's "Only One" about it-- the pieces change multiple times. Sure at the end you claim that you cant restart the game but all you have to do is close the window and reopen it... Other than that its kind of just chess with an added feature..? I don't know exactly how to feel about the game.
Yeah I know. I can explain how I got to the feeling that that's only one.
At first I thought about chess except every couple of turns, you change all of your pieces to only one type. But then I thought that that would maybe be boring, and maybe you should choose only one piece. I thought about that again and understood it doesn't really work for most people only the morning after the end of the jam.
