Great execution of the theme and really good systems at place.
The energy management aspect almost detracts from it, but it's probably a necessary counter balance, specially for the orange fields.
Very nice.

The energy is really a mechanism hard to balance. It is actually not designed for limiting the player, many effects requires low energy level to activate. Energy adds a variable to the music loop so that an 8 bar loop can automatically have different variations in different loops without player's modification.
