I'm buying this on Steam so I don't have to keep going to itch to download a new update everytime. Plus, I'm glad it's going on Steam.
To be clear, the Steam release will be a collection of versions 0.1 through 0.7 and won't include versions after that. Versions after that will be released in a separate collection in the future, either as a separate game or DLC. Buying it on Itch however will give access to future versions, as I will treat it as an early access title here.
