Improved my old Famtasia recording by 11.6 seconds. 15 seconds if you ignore the additional frames that FCEU adds between screens.
Extra tricks:
- Moving between screens isn't a smooth process. Hitting the edge with certain frames of animation gets you around faster. The best ones are the last step before a jump, and the last few frames before landing.
- Level 8: Jumped off the ledge on the far left instead of dropping down. For some reason hitting the wall prevents fall damage.
- Level 10: Jumped off at the end, taking damage, but using the wall to skip the landing delay.
