That has to be one of the most creative approaches to the theme I've seen so far! I would've loved to see what more you could've done with it. Perhaps adding some scoring, more levels or some mechanics. Well done though! Very nice little prototype.

That is an interesting concept, I have not seen another submission with this mechanic yet !

I have two little nitpicks though, in that using the XYAB keys on the keyboard was a bit awkward and I also was not certain if I had won or not at the end of the game.

The art and music are very nice !

Cute musical toy. Maybe could have leaned into the dice theme more by making the nodes be in the shape of standard dice pips. Where's the music from? It reminds me a bit of a track in Tetris Effect.

The music is so cool. Loved getting the music all playing. The neon vibe is also very nice. 

One thing I will say, is part of the gmtk rules state 

• You can not require the user to have hardware beyond a keyboard and mouse (so no VR games, webcam games, and no controller-only games). 
  

So while I appreciate that controller is better, I think most games won't use it as the main input due to this rule.

You do rotate a cube around, but this feels like it doesn't fit the theme. 

Despite my complaints, I did enjoy this one.  Feels less like a game and more like a cool art installation.

Cool idea
