A Well Done Demo
I am a big fan of the Exmortis series. I have beaten the first two and am looking forward to purchase the third. Until then, the demo is a decent taste of what is to come.
Sadly, most of the negative reviews on this are people whining about how the full game costs money. More specifically, how he's "forcing us to buy the full game."
He has not reached into your wallets and taken your money. He has not forced you to do jack shit. You are free to not purchase the full game, but complaining about how he has "sold out" makes you look petty. Do you complain whenever any developer releases a game and it has a price greater than $0? Because if that's the case, the real world is going to disappoint you greatly. Money is everything. People need money for everything.
But with that rant out of the way, the demo is still very enjoyable. The music is haunting, the graphics incredible, and the atmosphere is haunting. It's definitely worth giving a run through.
