They come from behind! LeL. It's very original. 

The pixel-art is awesome and the controls are very fluid.

Congrats! 

Solid controls and gamplay but tough. Well done!

Tough game - great job!

keep going! gg!

Nice simple shooter, with good graphics and good sound. Difficulty feels fair besides one thing, altho I don't think I survived for more than a minute. The thing that can make it unfair is that you don't know where the enemies will spawn. I think either changing the spawn positions to only be at the top, or maybe adding mouse aiming would really help in this. Overall good if simple game.
