Typogun is a nice typing game with similarities to Typomagia where you control a stationary turret. Type in the words above the invaders and hit enter to send a gunload to them. When powerups appear you can collect them with the same tactic.
Minimal is a physics based jetpack platformer where you have to collect 3 different colored diamonds to open the exit door. In each level you have to fight against gravity: You are either pulled towards the bottom, the top or to the sides. Moreover there are also many traps, obstacles and enemies to avoid. Nice game!
Riah is a little action platformer that pays tribute to the Castlevania series. Your weaponry: an extendable sword, an axe, a boomerang and knives.
The game is also pretty short and can be finished in about 5-10 minutes.
