This game is broken but actually lots of bad things can be avoided or used :

Annoying glitches (and how to avoid them)

• Keyboard is a pain to configure, easiest to play with a controller

• Don't hold "Accelerate" when reloading or going to the next level or your horse will flip around (just reload the level if it happens)

• When on a moving platform (especially vertical ones), always move forward or backward (little inputs work) so you don't clip through the platform. It's the only way to finish level 18. Portal without losing your mind.

Useful glitches

• If you stop moving, your hitbox kinda "disappear", so you can pass through moving walls or stay on a broken glass platform.

• You can boost jumps by doing two (or more) in a row, like in some 3D Platformers. It's kinda RNG but it's useful for a lots of skips. You can use some visual clues to setup the jumps, like the bone in Level 1 or the puddle in the Sewer.

Basic Tricks

• Use landmines to gain height. You need to have some speed and to jump to actually make them useful, like in Catacombs or Skyscrapper.

• To move around, stop, jump and change direction, it's the easiest way to go in the right direction without falling or something.

• It's more often than not fastest to Pause and hit Last Checkpoint than to wait for death so, abuse it if you need to.

• It can be faster to hit last checkpoint to place yourself optimally in some levels, use this accordingly.

• In Level4, Beach or Space, reload the level if the beginning is trolling you. Last checkpoint don't make the balls disappear, reload does.
