World Without End
About
Salvation in 45 seconds or your eternity is free!
The idea was to split the game into two halves: you would run around a huge map to collect as many upgrades and weapons as you can in 45 seconds, then you get to fight a boss. Every time you'd repeat, you'd refine your pathing in the first half. Do you max out your health to take more hits, or do you grab all the mobility upgrades so you don't get hit in the first place?
...that was the plan, anyway. Unfortunately, I ran out of time, so it's a very barebones experience.
