Thank you for the feedback!
So the damage: they do, it's just an insignificant amount of damage at the beginning of a run cause thematically, the asteroids get tougher as time goes in due to the glitch worsening. So damage taken is very low until like the 2 minute mark giving you leeway to grab some upgrades. By the 10 minute mark, every hit is disastrous.
The freeze issue: I couldn't recreate it. Can you provide some info about how exactly it happened so I can try mimicking that?
