Okay, we are tired of all these Slendy games, I get that. I myself didn't think this game was any good, and I didn't even plan to buy it. But the dev gave me a code to redeem & guess what? It can be pretty scary, honestly.
The icon and the screenshots look lame, but the game itself proves to have quite an atmosphere thanks to well-done music and voice. I don't mind the pixel graphics, it seems to be a favorite choice of indie dev these days.
Gameplay-wise, it's rather typical, and leaves me wanting more. Right now the game has no difficulty option, only one forest map (but it's quite large), and overall just not outstanding and unique enough to compete with other Slenderman games on the App Store.
Nevertheless, this game is no ripoff, and Slender fans should get this just to know that even when pixelated, Slenderman can still scare the heck out of you.
Speaking of which, "Slender HD" is a pretty funny way to name a 2D pixel game.
