Infectonator : Survivors [Steam store page]
The game concept/design is solid - scavenge supplies, rebuild your base, try to rebuild the car to get out of town - but there are a couple fatal flaws that really hurt the gameplay.

The main one is the AI - it's dumb as a box of rocks, and will walk through toxic slime (which kills the character in a few seconds) without hesitation, even when there's an easy path around it. Most of my damage and deaths in this game were due to the AI making stupid decisions.

And when a character "dies", they can be revived for around 15 seconds - which is fine except that it takes like 7 seconds to actually revive them. The timer doesn't stop as you're reviving, which means that if you get to the character with 3 seconds left on their timer, there's no chance you can save them.

It makes it frustrating if you're in the middle of fighting zombies and can't start healing immediately. I'm sure there are upgrades to make heals faster, but it's still a flawed design.

Just Get Through [Steam store page]
If you mash together the responsiveness of Super Meat Boy, and the randomness of Spelunky, you get a simple but satisfying randomized platformer.

Hotline Miami [Steam store page]
Prepare to enjoy smashing open heads with a bat, slitting throats, and shooting enemies at breakneck speed in a psychedelic environment.

Corporate Lifestyle Simulator [Steam store page]
This game was originally named and bundled as "Zombies." before being renamed and released on Steam.

I wasn't a big fan of the melee combat, but once you get shotguns and SMGs it makes killing the management a much more pleasant experience.

While this is a much cleaner game than And Yet It Moves, I am left wishing for better control granularity. In certain areas a mouse control scheme would reduce the number of deaths immensely. Luckily the checkpoints are frequent and lives unlimited

Minecraft in 2D, but with good combat and bosses. You can make a large variety of weapons and potions, and there are sky islands, dungeons, and the underworld to explore. The 1.1 update adds tons of content and improves the game considerably.

Revenge of the Titans [Steam store page]
A tower defence game that keeps you on your toes. There are tons of upgrades and not enough time to buy all of them - you definitely won't get through all the levels on the first try.
