Download Stealth Bastard (PC)</center>
Played a bit of this and really liked it. It's a stealth-action platformer with a bit of cheeky wit, some fun puzzles, and some intensely competitive time-attack leaderboards. From what I gathered, Stealth Bastard's main objective is to be a fast stealth game--it is! Doesn't cost a dime, either, which is nice.
In all honesty, it caught my attention because it looked like a game that could have been built using Construct Classic (with a bit of thought and hard work, of course). Stealth Bastard is quite nice and I'd suggest you give it a go.
