Delightful game! Love the vibe--kudos to your composer. The idea of your super move costing huge amounts of Charge is a nice elegant way to create tension.
Somewhere around level 20 I ran into a power pack that wouldn't despawn when I touched it. Immediately jacked my Power to > 1000, which was great, but the power pack was in a 1-tile hallway on the critical path :( Still, super fun and I'd play again.
