I LOVED THIS GAME!!!
I just have a little difficult seeing the hud visuals on the sides because they are a little tiny, and the buzzer sound of the constructor is very irritating xd
But everything was very good, very impressive that a game like this was made on three days, i loved the visuals.
The shoot that pierces everything but the block is a good choice of game design, because you can explode the grenades with your bullets so you can feel like a master of destruction.
