I investigated the new strategy that I used in the Stage 2 Boss, It's a
New Glitch that i just found out recently.
To perform this glitch (
Only Works With Tops in the Bosses of stage 2, 4 & 6),
you must shoot the projectile along with freeze attack both in the boss.
I checked my last WIP of the game and I made a mistake of improvement time. It's 526 frames actually improved, not 681 frames.
In Stage 2 before the boss, 71 frames is saved totally, not 222 frames.
EDIT: With this Glitch, it's possible to save time in Boss Stage 4 and Boss Stage 6, but is much harder to down cycles.
EDIT 2: I tested the glitch in Stage 6 Boss:

Normally with Tops, you need 7 cycles to defeat this Boss. But with this glitch, it's possible to defeat in 3 cycles.
Unfortunately, it's impossible to defeat in one cycle.
EDIT 3: I tested the Glitch in Stage 4 Boss:
http://tasvideos.org/userfiles/info/29710337800204236
Normally, you need 5 cycles to defeat this boss (because of long waiting when you hit this boss normally), but with this glitch, it's possible to defeat in one cycle (without waiting)!
