December Problems is a follow-up to 99 Problems, a blocky arcade action game that we covered back in September.
It's a simple, free game much like its predecessor, meant for anyone looking for some plain old twitch reflex action.
In December Problems, you control a block, bouncing from left to right and back across the screen.
Tapping makes the block leap slightly upwards. Letting it hit the wall leaves the block to bounce down.
You'll need to use both to your advantage, navigating the block around a series of static and dynamic obstacles to the eventual end of each level, which all flow together quite naturally.
If you don't want to download anything on your phone just yet, you can play December Problems in a browser on Game Jolt.
