The overall aesthetic is awesome, it's short which makes me want more but that's usually how it goes. Just a few points though:
- The Floor contrast, for me and a few people I know the contrast between the floor and the rest of the environment was a little too small. It was sometimes hard to see the platforms themselves in relation to the background.
- The shrinking mechanic was a little weird to start off with just because when I went into the area I assumed would shrink me after hitting the switch to open the last Cube's area it didn't do anything. Maybe making it a little clearer that you need the cubes could be helpful?
Overall though the controls are nice, the menu animation was cool and the visuals have a unique style to them. Really awesome short and sweet game.
