This isn't one of those silly discussions about "IT SHOULDN'T BE ON STEAM CUZ LITTLE CHILDREN WILL COME" but rather two or a couple more questions. (Hoped to get answered by Badspot)
1. Will customers who purchase Blockland through steam recieve keys (I believe so)? How will they get a key, will steam redirect the customer to a page that will open in their browser to get the key (not very efficient IMO), or is there some way Steam offers its own key generator?
2. How will customers who purchase Blokland through steam get their email registered incase they ever forget their key? Will it somehow use the email the steam account is associated with?
