(This review is based on the Steam version.)

Pit Blocks 3D is your typical 3D Tetris-like affair, and is pretty good excluding a bug where the Halloween Theme no longer works, thus causing the game to idle forever until you Alt-Tab out to close it.

However, I do not recommend buying this game. On April 9th, SRM Games revoked about 7800 Steam keys that, according to him, he thought were not used. Well, some were.

People got mad, SRM Games tried to defend himself, eventually he started deleting every negative comment from Steam's Discussions page, and he gradually became more and more toxic in his responses.

For an example, look up MMOFallout's article "STEAM SCAMS: SRM GAMES MELTDOWN AFTER FRAUDULENTLY REVOKING KEYS," and look at SRM Games's response. Here's a snippet:

"Do you sjw losers always shit on your betters cuz you'll never be half as good as they are?? Or are u just bottom feeders feeding off the misery of others even when they're at their lowest if this article is even half true?"

There is an archive of most of the main Steam thread on the IndieGala Forums.

Avoid developers who act like this.
Do not buy this game.
