B.L.U.

Cool game! The menu looks cool. When you hover the mouse on a button, this activates a second selection arrow rather than moving the first. A similar issue is present on the pause menu, but instead of an arrow, it's two hover colours instead. Pause menu UI looks really good!

Music fits the theme well.

Movement feels good. Though, it's difficult to see where you're going when under objects. Also, it's difficult to tell if and when a door opens. Sound effects and UI could help with this.

Colour mechanic is cool, reminds me of Hue. I to interact doesn't seem to be tutorialised until the broken door, which is too late since the robots give helpful tips along the way. The magnet mechanic is awkward to control, flings you towards the object and it's easy to get trapped. Dropping the object and throwing the object also seems untutorialised.
