Thanks for playing!
To address your points:
1. Yes ill fix this, probably something that detects if there are no upgrades on the scene and warps the player back if so
2. Yes I can do something like this
3. You arent the first person to complain about this, ill change that
4. The game is kind of based around the fact that the camera is a fixed position but as we playtest more I can look into changing that
5. 6 new asteroids are in the works including an exploding one that does AOE
Again thanks for playing!
