Here's what I have to say

Pros:
-Good pixel art
-Music slaps

Cons:
-When the videos said "make the guns have impact", they didn't mean have the gun shake the entire screen and destroy your speakers.
-The enemies falling from the sky is annoying and unpredictable, having them come from the sides of the map in waves would be better imo
-I didn't even know there were powerups until I read the reviews, some hint popups to indicate what things do would help.

With some polish this game could be pretty good for a browser game.

I can appreciate what this game is. You often do not see simple arcade high score games in the 2023 gaming landscape. Some polish will do wonders for this game.

My first impression of this was not good, so I'm glad I stuck around, because once I found that there actually were powerups and alternate weapons, I had way more fun. Please explain the controls somewhere. I pressed r out of habit, and that just restarts the level.

The art assets are quite nice looking. I like the details, such as all those people running away from the impending chaos at the beginning, and the environmental particle effects.

The camera shake gets incredibly annoying after a little while, but that's a minor complain.

Overall, this is a very decent game. A good 5 minutes of fun.
