If I buy the game here, will I get a steam key when it releases on steam? I want to support it but I'm scared the updates will happen on steam and I won't have that version
The developer stated that he wants to try to get everyone a steam key once it releases there. Click through the development log here a bit. I think he even has written this in one of the recent ones. Otherwise, get on the developer's official discord channel with the rest of us, we are a welcoming bunch and the developer is quite active there.
