Should I speed or should I not?

A small little game made within 24 hours for the Hyper Casual game jam with just two mechanics: slowing down & speeding up. Sounds quite simple, right? Well...

Theme:
Conundrum.
My implementation: should I slow down or speed up to avoid getting hit by incoming traffic?

Restriction:
Three colors. This one is quite obvious.

Controls:
Left-mouse button: speed up & restart when dead
Right-mouse button: slow down & unlock cursor when dead

Gameplay:
Quite simple really, avoid hitting the red squares that speed up and slow down at random intervals.
