You know that those red fruits make dash you faster. But is it like a trap, that gives you disadvantage, where if you use dash that you go further than you actually needed to go. Or does the fruit help you? Idk how toi explain it better sorry.

The red fruits are good.

They give a boost to your dash where it would be otherwise impossible to reach the next fruit. You might be holding the dash button for too long, try tapping it.

If you go further than you intend to, this means you hold the dash button for too long.
This is where they start teaching you hyper-dashing control mechanics, like not overreaching/underreaching the place you specifically wanna be at. Meaning you gotta' hold the dash button just enough.

It's part of the game mechanics, w/o red fruits it's nearly impossible to catch the next fruit. You can learn how to catch them by playing more, also do not hold the dash key all the time.

yes some hdash pattern is feel like a trap but there is no way to catch if no hdash mechanism, because catcher speed is fixed

u can practice control skill, press and loose (tap by rhythm) dash or direction key
