I would personally recommend that there should be feedback for the player when they are hit. I didn't realise that there was even health until i died the first time. Other than that it was really fun!

I liked it.

Cool little game, had fun.

Good job into making the game! It was a little hard for me but enjoyable :)

A nice twist on the asteroid game!

I would suggest randomizing the spawn point of the enemies a bit more (from the top-left portion of the ring you can basically keep the spacebar pressed and not move at all to kill any enemy)

Nice spin on the asteroid/space invader genre--I like the twist on going around in a circle.  It can be a bit hard to control in the beginning (kept getting my right and left mixed up!), but you incorporate it pretty quickly.  I'd be interested to see what other mechanics you had cooking up, but well done on getting a finished product out!  Very challenging to do on your own :) congrats 

Nice one, I got really focused on getting a good time, its the same button to skip the end screen as it is to shoot which meant I kept accidentally skipping the end screen and didn't know how long I lasted.

Fun core idea though, well done on getting this over the line on your own

It's an interesting idea but my main issue is that it is a bit hard to understand the gameplay and it is difficult to play.
I do understand that you didn't have enough time to implement everything you wanted to though, so I'm not trying to be nitpicky but say instead would could be improved in the future.

I think that the movement being having low acceleration made the game kinda difficult because I would stop to aim at an enemy and then slide away while slowing down and miss my shot. I feel like the movement could be snappier because there is already difficulty in moving around a ring as well as needing to line up your shot with the center.

Another thing that I didn't understand very well was the enemies. The enemies constantly move toward the player, so my first reaction was to dodge them and my second reaction was to shoot them. Dodging them doesn't work because they will just ram into the ring instead and hurt me, and shooting doesn't work because they don't die (Or maybe they have too much health to kill them before they reach). I think it's possible to keep them alive if I spin around them to keep them from hitting the rings edge but it doesn't feel like the intended gameplay.

Maybe to improve it, you could make the ring bigger and leave more space to react to enemies, and then make the enemies themselves easier to kill?
