I agree! Early supporters should get a steam key, especially when developers can make as many as they'd like with no cost and Itch users are a minority compared to the populous that would buy from Steam. This would allow all the updates to be in one place for early supporters who don't want to wait for the Itch.io updates. That being said, I'm also okay buying it again. I ended up buying the game again on steam; it comes included with the OST and they're working hard on making a multiplayer mode. In my mind for the Itch release, you're paying a fraction of the price for the original concept and version of the game. With the Steam release, they're creating a more full-game experience. Mike's other games aren't really given this level of endorsement or expansion, so I think the extra cost is warranted for that reason. So, I think either is fair for the developer, and no one's entitled to a steam key. It'd be a nice gesture though
I understand your point. However, I believe that those who supported the project early on should receive a free Steam key for the Steam version. Steam has a huge number of users, which means the developers could make their money back quickly. It's important to consider the early supporters on itch.io too, even though it's a smaller community, played a vital role in the project. Therefore, it's only right that us early supporters should have access to the Steam version as well. Therefore I firmly believe that us itch.io supporters should be given the opportunity to get a free Steam key, as a way to show appreciation for their early support and loyalty.
