Even though the game was simple, it was still enjoyable. The movement and the shooting was nice, and nothing felt too buggy. This is the first game I'm seeing in this game jam that has made a game with Pygame, so it's pretty nice.

I do have a few suggestions to improve the game:

 - The enemy wave spawning is a bit messed up. They all just spawn in a circle, so the player gets surrounded, and always takes a lot of damage.

 - The enemy health increases way too quickly. I'm not sure if it doubles or something, but a bit slower progression would be good.

 - The rapid fire powerups should either stack and spawn less often, or just not be able to be picked up by the player when the powerup is active. It's kind of annoying when we accidently pick two up, and they basically go to waste.

 - The later game becomes a bit boring. Usually, what happens is the enemies spawn, the player gets surrounded, has to take damage to escape, then the player just moves around in circles around the map to destroy all the enemies. This could probably be fixed by a more staggered enemy spawning, and more enemy types.

 - The upgrades could be more satisfying by doing upgrades such as multi shot, or maybe piercing, or make things like when they hit an enemy, they split up. The current upgrades don't really feel much different.

 -  The game also doesn't fit very well into the theme as said by other people.

 - The upgrades also start out wrong, but not much of a problem.

These are all the things I can think of right now. Even though it seems like a lot, I still think this is a great game for a game jam, especially since this is made in Pygame, which isn't like a game engine. I had lots of fun playing it even though it did get boring after some time, the first few minutes of playing it were good.

Overall, I think this is a great game, and you should definitely try to keep working on it after the game jam ends. 

Definetly did do a lot with less. As mentioned by others, wasn't on theme, and the game would definetly be helped by more content. Still, definetly had a lot of fun with it as is. My first survivors like game actually, and i didn't read the page so i was shooting with space and thought the direction was random which made it much more challenging(I did play it normal afterwards and had a lot of fun, just thought it was funny that it happened); Cool thing to try and find a way to slither out of the wave once they encompass all borders. And done on a selfmade engine makes it way cool. Good luck in the future!

That was pretty fun.  I got to a point where the enemies spawned in a solid ring around me and I had nowhere to escape XD.  It would be nice to stagger their entry times or something.  Good work!

Very fun loop, i can see this being a nice little game, off topic for the theme though, but sound design and player juice was nice, as other said enemy variety could've been better, but nice system for the roguelite progression, can see this being a fun incremental with the right art and twist to the gameplay

I liked the game’s music and sound effects. I don’t think the game really fits the theme. It would have been more fun if there’d been a greater variety of enemies. Still, overall, I enjoyed the game.
