It's not an FPS minus the S, the S stands for sprinter. Probably.
I like the idea of mobility-focused games, but I had some trouble figuring out where to make use of them. The "what to do" for each level was either pretty clear, or could be handily subverted by dashing upwards, which launched me into low orbit. There was also a bit of a lag spike in the green turret introduction level, possibly due to each laser having an individual dynamic light applied to it?
Still, I do like me some a-runnin' games. Congratulations on completing your submission!
