Well, we first are developing our games for windows. Eventually we will put it on Mac and possibly Linux. All PC platforms will be sold on Steam.
We would also like to put our games on consoles such as Xbox, PlayStation and the Nintendo Switch. However, these platforms have a longer process to go through to sell games. We will eventually (possibly) sell our games on these platforms, but there are licenses and other things we need to do before we can, so this is a low priority right now.
We do have controller support for our game so when we can sell on a console, it shouldn't take long.
