Bastard child between Super Hexagon and Undyne Undertale.

The game itself is fine, featuring cool music and visuals. But it's rather short with only 4 difficulty levels: 2 on the easier side, and the other 2 on the harder side.

Heavily recommended to turn off the background animations if you don't like seizures.

This game is also free with the "steamdb trick", so no excuse to give it a quick shot if you are into reflex games.
