Don't shoot the enemy!

My entry for the GMTK Jam 2018: Genre without mechanic.

Do not shoot the enemies in this shooter. Find instead another way to kill them.

I only had a couple of hours to make it, so no sound, basic cubes, and no effects. Just the bare idea.

Controls:
WASD - Movement,
Mouse - Aiming
Left Mouse - Fire

Nonetheless, have fun!
