Hello, fellow game developers!
The following is a link that will take you to a two player fighter which offers a free demo and the option to buy all the assets and code used within GM2. If you like some of the mechanics and the style of the game then you are free to make use of everything this game has to offer by paying $2.00 for the zip file containing all that it has to offer. https://oddginger.itch.io/two-player-fight-demo
