Slayaway Camp (Android)
An excellent puzzle game with a rather interesting voxel-based visual style and an appealing theme, namely that of slasher films. The entire game is a spoof of the genre and the time when it was most popular: each chapter is a different film, presented as a VHS tape in the shelf of a video rental store. Plus the menus resemble the OSD of a videotape recorder of the era, and the in-game rewind feature produces the typical 'static horizontal stripes' you surely remember unless you were born in the mid-nineties or later.
Gameplay-wise, it couldn't be any simpler: you've got to kill everybody in the level (cops and spec ops excluded) and reach the exit point. But your characters (the serial killers starring in the different films/chapters) can only move in 4 directions, and once they start moving they won't stop until they reach an obstacle. With that movement limitation and a bit of clever design on the developers' part, you'll be in for a lot of really challenging levels, where you'll need to go round and round the level before being able to kill an elusive victim.
I think this game may be an excellent entry point to the genre, and not only because of its theme and gore. The first levels of each chapter, where a new game element or mechanic is usually introduced, are quite easy and straightforward. And then, there's an in-game two-tiered help system: you can pay a small amount of coins to get a hint (e.g. "you should leave the victim at the bottom right for last"), and if that's not enough for you, for a bunch more coins you can be shown the full solution. I had to ask for a hint a couple of times, and only once I needed the full solution. In my defense I'll say it was literally the last bonus level of the final chapter, which was particularly long, complex and far-fetched. But other than that damn level it was fun all the way, so I can wholeheartedly recommend the game to any puzzle and/or slasher films lover.
I played it on Android as I got the game in a previous Humble Mobile Bundle, but you can also find it for Windows, Mac and Linux
on Steam, where there are also a lot of DLCs that don't seem to be available for Android (or for the Humble build, at least).
