itch.io

at this point I believe that I have found all the objects due to there not being anymore quest. Although is there a way to tell if you have unlocked all the commands or what commands are there? 

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?

I recently just purchased the game which is still an alpha version does that mean i will have to purchase the game again when it comes out or will it just update
