Tips on beating Horizon

During the bossfight, the lasers kill you only when they flash. Their hitboxes are a little big (using LDM in this fight will show you how big the hitboxes are to make it easier but the level looks uglier that way). Also watch out for the fire around the boss, as it kills you too. Other than that it's just a matter of memorizing the boss.

it's really hard to tell you exact seconds by text when to click and when to let go.
As Ezel said, the lasers only kill you when they flash, but the fire surrounding Anemone kills you too, so don't expect staying at the top or bottom of the screen to save you.
just keep trying to memorize the last part where the level starts throwing saws along with the lazer and try to find the pattern.

Last Tip:
BE PATIENT, KEEP RETRYING. Replay the hardest part over and over again on a copy until you're comfortable with the pattern, even if it takes you hundreds of attempts. And this doesn't only count as a tip for Horizon, but all demons also.

Thanks for the tips. I just beat it with 820 attempts. I fluked at the end and almost hit a ball of spike

Horizon has a highly customizable HUD, where you can tinker each and every individual aspect of what shows up on your screen. If you pause the game, select options, and scroll down to HUD, you can either finagle your specific preferred settings via “Custom” or you can set-up a dynamic HUD. I prefer the latter, because it gets rid of everything unless I press the touchpad—so I only see the HUD when I need it. Before you take anything on, pause and take stock of the situation by clicking in the right stick. The game should show you any immediate threats, as well as elemental or armor weaknesses. You can also use this menu to ‘tag’ enemies with R2, so that you can follow them outside of your Focus with ease.
