RED



http://armorgames.com/play/349/red

An easy to learn skill game where you control a turret and have to ward off falling black orbs by shooting at them so they change their direction. One hit, you die. But there are shields, weapon upgrades and additional turrets that will help you along the way. Also the music is very... psychedelic.

Epsilon

What a nice puzzle game this is. A lot of inspiration seemingly came from valve's "Portal", but Epsilon certainly has his own unique style when it comes to solving inter-dimensional puzzles with a ball that needs to be sent through a portal to complete a stage. The concept is also easy to grasp, so you can play right away.
