Unfortunately I could not finish the game, I did not have much time to develop.
I combined the FPS style with a Matching Sequence.
You need to shoot the cubes when they reach the gray area in front of you. Each hit cube earns you a point. If you let a cube pass you lose life. You lose and restart the game when your life reaches zero. Cubes are coming up faster and faster.
Game made in Unreal. At the moment I am learning the tool so I could not do much, but what I was able to do already was a great learning
