Creators pour their blood, sweat, and tears into their creations. Games take a ton of work, and it isn't like it's a full time job that pays. All of this is essentially a labour of love. 

Sooooo the passive aggressive "ohhhhh no looks like it won't get finished" is both insulting to the creator and even potentially disheartening. You're really complaining about, essentially, receiving free delicious cake?? Just because it's a slice and not the whole thing. 

¯\_(ツ)_/¯

If you're really looking forward to the development of the game, then show your appreciation for what's available. Offer your support and share what you liked.
