This is a really simple and well made game! The border teleporting/looping really make the game shines 10 times more!  I manage to get 460 point first round! 

I really like it! The look, sound and feel remind me of Combat on the Atari 2600, but the movement is faster and the game more intense. I also like the SFX and music. Did you make the music? Perhaps inspired by the old game on the Atari mentioned above you could add obstacles and local multiplayer!

Nice top-down shooter! The controls felt good as well as the sound effects and it was fun to play, especially later when there were a lot of enemies. The game was a bit easy though, probably because there are not enough enemies at the beginning and because you keep your score after you died.

Fun concept and the existing mechanics are very well implemented. The play character moves fast for my liking. I often felt as if I was unable to aim when moving at the same time. The graphics were lacking, and the contrast between the player, the enemy, and the background made it hard to distinguish between the player and the enemy when playing.
