After finishing the first two levels (levels takes several scenes), I've started to reimplement various tricks and about to compile best routes.
Subpixel over carries on screens: 1-2 to 1-3, 1-3 to 1-4.
Comments. First level, first screen
- Starting with throwing a bomb for self boost is 49 position slower (considering you are going with 576 units, it would take 22 frames), so we are abusing the most optimal in both timing/position is the 2nd falling bomb.
- Since you need to get 0 speed to bend over for the key, best strategy is throwing a bomb and boosting for the end, because the setup doesn't takes much time and as previously mentioned, it get's efficient in long distances.
Second screen
- Climbing stairs depending on your position where you hit the stairs, usually the fastest method is A*4,U*4,A*4 because of the tinier better Y/X position trade between jumping and climbing to barely reach the next platform to continue charging to top speed.
- Most optimal exiting is always same length. Subpixels and maybe stair orientation alters the usage of U over D
Third screen
- Using optimal subpixels to get an additional speed gain to jump off without falling down
- Since you can't avoid red spike, jumping when only hit once is the best and continue holded speed instead of 384
Fourth screen
- Picking up soda can because we are thirsty
- Throwing a bomb to boost off and jump over the huge gap which otherwise hard because of the great hitbox of the red spike above your head, you also need to time your dmg to avoid your speed getting zero (as you run out of health while charging).
Fifth screen
- Currently optimizing best X and Y pos for first enemy's bomb to boost off and Bullwinkle's position to avoid further chainsaws. Just running to the right ends the level at 3085 with 576 units speed (goof jumps are not abusable to get 640 units speed)
Also I have no idea if there any use of bombs other than boosting off and killing enemies (especially since you can't combine this two, you either boost off and get dmg or you dmg someone else and cry in a corner for no extra speed).
