Very good for your first game! I couldn't get the sacrifices to work, however. Not sure if that was a mistake I was making or what.

You usually don't want to give projectiles a rigidbody since they'll just be colliding with other rigidbodies anyway, which still fires the collision. Because they have a rigidbody they can collide with each other and some projectiles will get stuck.

I don't really understand the point of the time travel mechanic, but it was very well implemented nevertheless.

Well done!

Interesting game! Seems like the bullets are affected by the ship's velocity, which makes shooting weird.

Not sure I understand the connection between them leaving and sacrifice but a good first entry. Clean and readable :)

I was a bit confused with the sacrifice mechanic. Didn't work for me for some reason. But even without it, the game brings a nice challenge. I also liked the time reversing. :)

Nice little creation! The time rewind feels really cool, but there are a few glitches with it that can be exploited to guarantee victory. Whenever you are damaged by a projectile, the projectile despawns, and when you rewind, the projectile reappears but doesn't rewind. I also didn't like that projectiles collided with each other, as often enemy bullets would clump together into a cloud when ships travelling in opposite directions fired. I would have also asked for more diversity in enemies, as the one got a bit monotonous.

The graphics weren't the best, but there was clearly effort put into it. Could have used some music and sound effects, but the game was ok without them. Nice submission, keep it up! :thumbsup:
