Fire Boy and Water Girl

Fire Boy and Water Girl is a game that combines a little bit of everything. It's mostly a puzzle-strategy game, but it plays a little bit like a jumping action game. Fire Boy is controlled with the arrow keys, while Water Girl is controlled with ASWD. It involves a bit of multi-tasking, and sometimes you have to think about your strategy, which makes it a pretty fun way to kill a few hours.

Play Fire Boy and Water Girl.

Corporate Climber

A different kind of corporation game! This is a simple, avoid enemies and complete tasks game, but it's easy and fun. You move from the sewers to the top floor boardroom, and as you proceed, you face new challenges and different backgrounds. It won't take you long to get to the top, but the ending is funny and you can go back and replay again and again.

Play Corporate Climber.

N

N is a simple, fun game (somewhat like Fancy Pants, but a smaller character...and no pants) where you jump through obstacles to collect coins and move through doors to the next level. It's addictive but challenging, and great whether you want to play for 5 minutes or 3 hours.

Get Off My Lawn

Get off my Lawn is a challenging level-up game where you have to defeat all the monsters before they destroy your lawn. It's multi-leveled, and will keep you busy for a while. The enemies have different abilities, so you'll have to adapt different strategies for different levels.

Play Get Off My Lawn.

Kids vs Ice Cream

Kids vs Ice Cream is a unique game where you're an ice cream truck trying to take out the vicious kids of the neighborhood. You start with a pretty basic truck, with pretty weak ice-cream gun. But by the end of the game, you have multiple guns, a Popsicle missile shooter, and the coffee toffee cannon of doom (because kids hate nothing more than coffee ice cream).

Play Kids vs Ice Cream.

Indestructo Tank

Indestructo Tank is a great random/level up game. You play as a military tank, moving through a field while air forces above you attempt to drop bombs on you. The catch is, you want to be hit by these bombs, and launched into the air to destroy the planes. It's a fun action game, but strategy is important, as you want to maximize your combos while not running out of gas. Also, you have to chose which aircraft you want to buy (there are 5 options), and there are differences between the bombs they drop--so chose carefully.

Indestructo Tank 2 is here. (I don't think it's as good as the original...too much going on...but if you like #1, try it).

Hedgehog Launch

If you play online games regularly, you've probably run into 'level up' games (my term, I haven't seen it anywhere else). They're games where you have an end goal, and you work toward the task, usually earning money or points, to level up until you can reach your final goal. Hedgehog Launch was my first true level up game, and I haven't seen any that quite measure up to it. It's slow going at first, but quickly you get better launches and rockets, and soon you're zipping closer and closer to the moon. I love games that have a nice ending, and this one certainly does.
