It was an interesting concept and use of the limitation.
But I feel like there are bugs that kind of spoil the experience and the character feels too random for me.
I liked the complexity of commands (colors), but it really needed an playable tutorial to let players get used to it slowly...
And I think it would be nice to have 1 or 2 colors being the main commands to move the character while the others being kind of a support command for some novelty encounters.
