Cool idea for a unique projectile mechanic. I loved the maths theme and the audio was fantastic! I think the main thing it's missing is a restart-button, and some way to tell what part of the sine wave your bullet is going to go when you fire it. Great job you should be super proud! 

What I liked:

Core idea

Jokes (the funny sounds and lore)

What I disliked:

Lack of feedback, e.g. the hp of enemies, lack of indicator to show when the shooting cooldown is finished

An unintuitive and clunky connection between movement and shooting: you shoot with the mouse, BUT the cursor pos does not change the trajectory at all, only movement does

Art, it doesn't look appealing at all. I guess it sorta fits the joke aesthetic, not my type

Hope you do better in the future! Never give up!

The bullets move in sine waves! I think you can do better in one month though, good luck next time mate!
