Since it's the weekend, why not download some stuff? Come on, it's not like you were actually going to clean the kitchen or cut the lawn or finish that book on quantum physics you've been leafing through in the bathroom.
INVADER INVADER (Windows, free) - An experimental arcade/strategy game made for the No More Sweden game jam by Arvi Teikari, a.k.a. hempuli. Flying your little ship around, your job is to destroy the giant invaders by pecking holes in their hull so you can gain access to their soft innards. Once you've taken out a few turrets and have cleared a safe space, disembark and walk around the inside of the invader, seeking out computer terminals and eliminating them to disable the big ole baddie. It's a delightfully engaging concept that, even in its unfinished state, will capture both your attention and your imagination.
Time Squid (Windows, free) - A crazy and precise arcade game from Lazy Brain Games that's about as forgiving as hand grenade. Pilot the tiny squid through single screen levels as you attempt to make it to the goal in as few attempts and as quickly as possible. Try it, see how fast you fail. Also see how many times you keep trying! Even though it was inspired by the game of gold, don't think for a second that it's slow-paced, dull, or in any way involves those awful pants golfers always seem to wear.
project ARK (Windows, free) - A tiny little adventure made by Suntoad Games for Game Boy Jam. You play as a .NOAH, a machine who goes out to explore a world of rare animals. Explore the delightfully green and less-green world as you converse with certain critters and scratch your head over others. Giant tortoise that turns into a, uh, "frog"? Check! And that's not even the weirdest thing you'll run across!
