Serious Sam: The First Encounter

I bought this game I think about two years ago and did so in first line to support the developers. This is what GOG and the developers on GOG aim for. I also expected to get continued support for the games I buy at some level. Now I find out there is a HD version of the game, not even available on GOG. The HD version has NO major improvements. The main thing about it is the ability to select higher resolutions. This is exactly what I meant with continued support, but to get it, they want me to buy the game AGAIN! I'ts a ripoff! I expect GOG to protect me from such ripoff strategies. If people feel betrayed, what do you expect them to react like? I sayd it before and I say it again: If the developers aren't fair, why should I?

Yeah, ti looks nice, but this game is an exercise in pointless frustration. Not enough health, monsters that appear from nowhere, monsters teleporting in EVERY time you pick up an item, monsters that do 50% damage in one hit, monsters teleporting behind you every time you walk down a passage... I'm looking for what's supposed to be fun in this game and I just can't find it. The entire thing seems to be designed to piss off the player with its unfairness.

I got this for free but every time i try to download it, it gives me server error

Not sure why anybody would buy this when the HD version is only about $5 more

There is an article on Flipboard that this game would be free until 11 pm tonight. Was the article incorrect?
