Horrible because it was frightening or because it was a poor game?
The only horror game I've ever played is Dead Space, and I don't find it really frightening. But I'm waiting to play Outlast to see :)
And thanks anyway :)

I'd have to say Journey of the Light...
It's advertised as one of the hardest games on Steam, and I suppose it is. Mainly because there's no clue of what to do, not that there is much to do, and recently some people found out there doesn't even exist anything past level 1. The only one with any game badges is the developer himself.

Thus far, Bad Rats, followed by Woodle Tree Adventures. I also found Of Orcs and Men to be unenjoyable, but that may just be my own tastes.

I didn't play really horrible game, because I choose games carefully.
I know about game "Air Control" on Steam ( now probably taken out of Steam) which is clear rip-off on gamers.

I don't think I've played any "horrible" games. I do own a few bad ones, but I've never actually played any horrible ones.

Vigil: Blood Bitterness

It is confused and buggy game...

Retention. Basically a PowerPoint simulator.

Thanks

Dead Bits

I personally hated And Yet It Moves

I actually once played a copy of the infamous E.T. game on the Atari 2600. It was miserably bad, but I still couldn't complain because I got the system and everything with about 30 games (many of which were good, like COMBAT! and Air Sea Battle) for just two bucks.

guess it was some indie game dont remember the name but it was so bad made

HarmoKnight. Maybe not the actual WORST game I've ever played, but I absolutely hated it with every fiber of my being. To think it was made by the people who make Pokemon. Getting 100% on it was painful and not fun in the slightest. Actually, none of the game was fun.

Of the top of my head, I would say Bad Rats. I'm sure I could name a few more, if I looked at my games lol.

Pixel Puzzle, both Japan and UndedZ. The controls are really clunky.

Uh... I'm excited for the future of this game but currently.... Sirius Online.

Can't tell where you're going, jerky flight, empty space [no one online].

Makes for a very boring game but, as long as the devs don't give up on the game, I'm sure it will evolve into something amazing.

Le fael!

Dead Bits, I had a headache in few minutes because of it.

Karateka. It seemed fun, but was very, very boring.

The worst game I ever played: the one where they dare you not to say thanks or they'll blacklist you... usually I can't help myself and say thanks because how silly it is. Naturally I ended up on some blacklists because of this.

Sometimes when I do it like this the people are still sour and I end up on it anyway... So it's pretty much a game you are certain to lose.

Anyway here goes: Thank you.
Hope I didn't offend you with my appreciation. ;P

In all seriousness: It is a bit sad that we ended up with this system. Since now because of it, it is almost a better practice to not say anything at all... because you never know what kind of response falls into the giveaway creator's approved list.

Bad Rats - even run it for cards is nasty and delivers complexity.

thanks my frd.
