I thought this hard badge would require some backtracking to get all the missing stars. Turns out there was extra stars and I got the 20 required before beating the game?
Survival. 40k meter. I think I'm running faster than the jetpack. The second boss doesn't even have time to land. I have no idea how the Spider boss can walk so fast. Supports don't even stay on-screen half a second. And staying on-screen is guaranteed smash into a wall. The best choice: cowarding off-screen.
