Survive as long as possible inside a collapsing black hole while waves of aliens attack you. Beat the high score!

Premise

Claustroshooter is an action game made in 48 hours by manta ray for the Ludum Dare 54 game jam, on the "Compo" format (make everything yourself in 48 hours). The theme was "Limited Space".

What's the deal?

You somehow ended up trapped inside a collapsing black hole. Fortunately, you have a weapon which fires space expansion bullets, that can make it a little bigger.  Shoot with them at the black hole.

Your weapon also includes regular bullets for attacking aliens, who are not amused you're invading their space, so they are teleporting in waves, to kill you. Shoot aliens with them.

Take into consideration, shooting regular bullets at the black hole will make it collapse faster!

Your goal is to survive as long as possible (and earn points on the way) by not getting crushed by the black hole and by killing aliens.

Scoring

• Enter your name in Options so your desired player name gets into the leaderboard!
• The black hole will get smaller and smaller. While the black hole is YELLOW, it gives constant points. The black hole does not give points if it's too big.
• Kill aliens to get points.

There is a tutorial which explains the controls in game (note you might have to re-enable it in Options), but here they are as well:
