![[PC] Free Game: Son of a Witch (Was $11.70 AUD) - Steam](https://files.ozbargain.com.au/n/48/458848.jpg?h=f5875d88)
This looks like a fun game to play in short bursts - it is a rogue-like game and I assume it can be quite addictive ("one more go", "only 5 more minutes"…).
It is rated at 85% positive ('very positive') on Steam.
Given the download size of 600MB you can get playing fast and 2 days I assume would give you the chance to see quite a bit of content of the game.
Enjoy!
