I'll add to the Q&A here as I get  more questions!

What are the enemies based off of?

Most of the enemies are just random animals I made pixel art of LOL. The animals started out being food-related animals similar to neggpals, but eventually it became just random animals, and some enemies and assets I've made for other games. And some enemies are also references, like the amogus, ants, and the last enemy that spawns (no spoilers).

How do you win the game?

The game technically ends at 30 minutes, and you get the trophy for achieving 30 minutes. However, the game still can be played past 30 minutes, it just starts getting exponentially harder.
