I was intrigued by the thought of this kind of challenge run, and so I made a video of the first level. Garcian is a tough guy, but playing as him comes with a fair share of problems. Both logistical and offensive problems. Some annotations throughout the vids sprinkle some insight into the strategies and what exactly makes this run type potentially difficult.
Rules:
- Garcian is used whenever possible
- other characters' only function is to solve puzzles (and absorb hits)
- no upgrading
