So I asked this question before but it seems that if someone bought the game from Itch.io that they still need to buy the game from steam as there is two different versions. Although will the full version that is able to be played with a keyboard and mouse be uploaded so people from Itch.io can download it?

Based on https://twitter.com/TinyHat_Studios/status/1299454523694604289, there's no Keyboard and Mouse support for the steam version currently, and there's absolutely no information on what version has released to steam compared to the current itch build. I'd hold off until we know more information. 

I've just taken a look at the steam version, and I'm pretty sure there's no change. All the bugs and issues present in the release over a month ago here are still there. I do not recommend purchasing this, especially considering we've had no comment from the devs in regards to future updates.
