I've never seen this type of game before. Interesting take on running out of space, though. Could use some music, but you're new at this, and this is probably your first game jam, so what can I say.

For a first try at game making, this is a solid entry! adding a bit of sound would have helped get the mood together but found me playing it for quite a while.

Good job.

Hope you learnt something during this LD. As said before, you could add some sound effect, maybe some features. but hey, if you are new, its alreary a big challenge to release somhething working without bugs.

can't make it past 44 seconds

My record was 40 seconds, it's a good game, lacking music and sound effects, but it was still a great experience!

Good job on your first LD entry. I imagine you were running short on time, still a solid entry. The shooting animation looks surprisingly juicy. :)

I don't think the lack of sound is the biggest issue with the game. As it's often the case with this genre, standing in a corner and spamming is the most viable tactic, basically breaking the game.

Keep up the good work.

Nice game, Love how everything is balanced!
Good luck, Don't forget to take a look at ours if you don't mind and see what it's like when we just focused on graphics in this game jam!

Good game, nothing wrong with it other than needing audio and screen size settings.

Good job! That's a very original idea in this jam :P

Good job for a first-timer.
A few things to add if you intend to:
- Health: for the player and the zombies
- Healing: through some kind of pickup
- Spawning: zombies should be spawned outside of the circle, not inside and invincicle

The best strategy for me is just standing there and shooting in circle.
Moving around would risk touching a Z and kill me.

Keep on making games!

Great first-time-jammer game!

Firstly I offer you to make some changes in spawning(Like @dleanjeans said).

Secondly add maximum distance that bullet can fly. You can play as long as you want if you just run spin and shoot.

Anyway, good job!

Really interesting - really hard. The mechanics are smooth and all works well as expected. I think that you could allow to players a short time, just to prepare the battle. Maybe nothing should happen until the player touches the first control key - or a decreamenting time lapse. Instead all enemies rush quickly and I have no time to escape. The fog around player is a good idea - something which fits with the theme. A good entry for a first attempt. Bravo ++
