Fun little game! I did not see the real differene with the different colored ghosts, but blasted them all anyway :)  An indicator for when ghosts were behind you would have helped a lot with getting hit from the back, in the end I ended up using an outwoards spiral move pattern which minimized the risk of getting hit from behind. Thanks for the entry!

I'd say you've got some good core gameplay here with trying to deal with the large number of enemies and weaving through them to get the power-ups. But I do think it would help to have more feedback about when things take damage though, like have some hit particles/hit sound when hitting the ghosts and some sound/on screen effect when the player takes damage as well. Aside from that, I also thought the gun was a bit static, it would be nice if there was some animation for reloading, or a kickback when you fire it. Either way, what you've got here is still good, nicely done.

Solid little arcade style FPS! Felt satisfying to blast away the ghosts! The music had me on edge!

Nice shooter! I had good feelings! Check my shooter game too!

Really fun! I found it a little hard to tell when or where the ghosts were coming from (or maybe I'm just a bit slow at turning with the mouse!), but it has an addictive game loop that made me want to keep trying one more time. The ghosts look really cool too :D

It's not my genre, but I like the combination of art and music, I got lost in the waves, just figuring out by the shadows where ghost hide. Seems I am not a cowboy after all :-)

Good Job!
