Very simple game. Reminds me of old Atari games, which is good. The game is too hard from start. I would recommend you to ask your grand mother or grand father to test the game. If they can't  finish the first level or stage, then the game is too hard. 

Also I would like to be able to steer left and right, not just up and down. Finally the star field in the background just look weird. Why are the stars not going in the same direction?

Nice gameplay, could've made the enemy ships explode though, missed opportunity. It was good and enjoyable. Well done :)

The gameplay and the concept are very good but 

projectiles

are to slow

I like the gameplay, but the sounds are really annoying.

Little buggy with the shooting mechanism, When I killed 2 red ship, It would kill me... All in all a fulittle addicting concept, could get more polishing... Keep it up...

Thanks for your feedback!! I'll release a second version with more in the future!!

This game fits the theme very well, having to balance the red and blue kills. The game is confusing at first since the fire buttons are not obvious and aren't in an instructions file, tutorial, on the itch.io page, etc. (they're O and P, had to check every key). The sounds are kind of lacking, only the clicking noise in the background and a simple firing sound. As for aesthetics, the orbs in the background are nice, really adding a bit of immersion. The ships, however, are all recolors of each other. It would be nice if the player's ship looked different. There is also no health bar for the player. The best way to improve this would be adding more sound effects, like an explosion when the enemy is destroyed or when you are hit. Some particles would also look great.
