This is my second attempt at LD38, and I've got to say, I really like how it turned out!

You control a tiny circle in a small planet, that is constantly shrinking. You have to kill some enemies for the world to grow a bit, but when you do, the world shrinks faster. You can play the game here. Have fun!

Here's a gif of the whole game. It's too big for the website to handle, so you'll have to go to the link yourself. :shrug:
