Glitches

Known glitches:

For any% and 100%
9: YamCider found that the red barrier can be clipped through. It is very precise (frame perfect?) but it seems to involve, when jumping off the platform prior to the barrier, jumping very late (when it actually looks like the character has already gone beyond the edge of the platform) and only soft tapping jump. Then, when the character comes back upwards, push right and the character should clip through the barrier at the top.

For 100%
5: To get on the ledge above the red barrier you have to double jump off the first platform. You can then simply double jump over the wall (off screen). 
12: Jump to the furthest upper block for the pill, then single jump off that block and pull right as you drop. You can then walk right (below screen) until the level is cleared.

How to Do the Level 16 Glitch

I tried my best

level 17 time save glitch

This glitch is frame perfect, and extremely hard (it took me 4 hours of trying to get this clip) but it is possible, and it saves time (if you can get it on the first try xD)

Level 6, 8, 11 time save

If you spam jump very quickly you can gain great height, and skip levels six, eight, and eleven.
Doing the glitch in level 6 lets us grab the pill earlier than intended.

Doing the glitch in level 8, right at the beginning, lets us walk on top of the screen to the end.

Doing the glitch in level 11, on the middle pillar, lets us walk on top of the screen. (Is faster for sure, but is a run killer)

I've found more success with this glitch by using it at the beginning of a level. Namely resetting on level 6 to get the pill seems to be more consistent than the rest.

The faster you perform the glitch the more height is gained (With a cap of course). It is very difficult to perform consistently. May be easier on mobile, which it does work on. (Mobile makes the glitch easier, but slightly different to perform.)

Can't get it to work on the Havana website HTML version. (This is probably because of the HTML version being optimized more than the other websites)

Fun fact: You can get onto the character art at the end of the game with this trick
