Antecrypt was pretty fun. "Single stick shooter" where your crosshair bounces around the level as you play. You need to stop shooting and get close to your crosshair to recharge your ammo. Good looking game with decent sound and music. Some of the enemies can be very frustrating to fight, especially if your crosshair won't cooperate. If you do play, be advised that you can use your upgrades by pressing down on the dpad after selecting a level and before launching it. Upgrades are consumed if you beat a level with them. I beat it in an hour and a half.
I think it's worth a play, it's a nice little game and it's short.
