I just bought twice,it's not expensive...
It's not the money, we supported this game at the beggining so we should get a special treat. At least a discount in steam to buy it
Brother you already have a special treat. You have the full version on itch.io for 1.20$. Who gives if you don't have the steam version.
The steam version has more features and will eventually get multiplayer, the most requested feature.
Who says itch.io will not have those features? It's not hard to create a room code based multiplayer lobby with scoreboards.
