Unfortunately com.android.systemui has stopped

[AC Question]

I got this message after installing this app and now, my phone is unusable.

I've got a Moto G 16GB XT1033, stock 4.4.2, unrooted, locked boot loader. I installed this game (https://forums.androidcentral.com/e.../store/apps/d...d=com.glu.dino&token=_bRqSUK9) and went away for a bit while it was being downloaded. When I came back, AcDisplay had the notification that the game was installed. So I dismiss the notification and enter the pass code to unlock the device. That's when the trouble started. I got the message that the com.android.systemui process had stopped. Everything would disappear for a bit and then its back to the lock screen. I tried rebooting and a dialogue that 'Android was upgrading' and 'Optimising app 1 of 1' would show for a while and then it would reboot itself. This time, the boot animation would be all wonky but it would get to the lock screen but if I enter the pass code, the systemui message appears. I tried safe mode but no dice.

How do I go about solving my problem? I just think its ridiculous that installing an app from the Play Store can cause my phone to be unusable.
