An interesting idea. Having to balance finding enemies and shooting them provides good tension. I felt that the theme didn't shine through; the one button was more of a hindrance rather than adding to the tension. There also isn't a score meter (that I could see) to allow you to compare between runs. The implementation reminds me of a radar scanner, which is very effective. A satisfying "beep" every time an alien is detected would add a lot!

Simple, pretty enjoyable, I like finding them I agree it needs polish and juice.

Neat idea where you see only one enemy. Forces you to find them, instead of just shoot at them. Could do with more polish and juice, but solid entry nonetheless.

Simple but pretty smart and enjoyable game. Good job !

Very simple but fun. Being only able to spin in one direction makes over orbiting very punishing while not unrecoverable. My highscore was 48. Btw always make sure to make a button on the main menu to exit the game, it is just as important as the start button. Not everybody knows alt f4 to force close. But besides that good job :)

Pretty simple and very straightforward, I like this one!

Design is simple and straightforward. The game mechanics adhere to the theme "Only One" where you will be pressing only one key (spacebar) and you can see only one enemy depending on your position. Feels classic and arcade-y. :)

This is really fun, and very very unique :D

Lol not sure thats how orbit works , but fun game.

I quite like this. Takes a bit of getting used to in order to get the ship to land in the right place, but that could be good or bad. This would make a pretty good arcade game. :)
