MareQuest

What exactly is "MareQuest"? First and foremost, you play as a mare. But don't get stuck on the idea of being a mare: you are also a pony, with cool abilities you can unlock as you progress through the game. You live in a land filled with other mares. Each mare has their own randomly generated personality, dialogue and style. The goal of the game is to help your mare friends become the best mares they can be. You can customize your mare to be as unique as you want, with options including wearing socks or not, and wearing a hat or not. 
As you progress through the game, you will unlock more abilities, also known as "mare perks". There are over 9 mare perks in the game, including ones like "fly faster" and "make poofy clouds". Some abilities are more useful than others, but each will help you towards your quest of befriending mares, while also helping you push back the Shadow Horses. Will you be able to stop this evil, or will you instead show off your sick dance moves at the Poni Poni Club? The choice is yours!

Bank of Equestria

Bank of Equestria is a fun little arcade shooter game created by ReconProbe in which you play as the Appaloosan Sheriff and defend a newly opened bank, while also protecting the amres from bandits. Be careful not to shoot the mares since mares are not for shoot.
The game looks great, and while it may seem simple at first, it really picks up after each level, introducing new mechanics and features that help keep the game engaging and truly tests your reflexes.
"Appaloosa's opened its first bank and investors from all over Equestria are tripping over themselves to make deposits. Naturally, every outlaw and villain worth their oats is gonna want a piece of that!
It's your job as the Sheriff to defend the bank by defeating the bandits and letting the good ponies go about their business unharmed.
By the way, there's a rumor going around that the lovely scent of all those apple pies has attracted a swarm of adorable, but dangerous creatures... 
This game is based on the classic Sega arcade game, Bank Panic."
