Haha, a blue neon square chased by angry red triangles. For some reason that made me smile. I kinda kited the enemy around the edges of the map for a while, until I couldn't get rid of them fast enough and they got me at the corners. I managed a high score of 1331.
That was fun, as others have mentioned before, just changing the health bar of the enemies to be red might help with distinguishing from the barriers in the game.
