Antenna is a short, slow-paced, atmospheric LIMBO-esque puzzle game. It has no introduction, no menu screen, no backstory and no explanation to the puzzles.
The visuals and audio is well designed and looks very nice, but the puzzles and gameplay offers nothing too interesting or fun. If you like these sorts of games, go ahead; but the only reason to play it is really just to get another Perfect Game on your list.

Terraria is a great game with hundreds of hours of content to go through. Even when finishing the game, there are always things you can do to keep having fun. It also goes on sale often which means it is well worth the money.

It's an okay game, I guess.
