It needs to say what level you were on when you die.
I don't know what the "rubber bullets" does. Why is that even there? I think it might've even made my shots weaker. Edit: Yeah, it makes the bullets useless. This should be removed: Absolutely terrible. There should at least be some warning about what it does, because It's confusing and it will instantly ruins every player's run. It's not even a real upgrade.
I completed all 30 levels twice.
The health upgrade does not "need a buff", especially since it also heals you.
Short, 5 minute game.
I don't like how it's so luck based with the cars; sometimes there's no way to dodge them in time.
