Thanks for playing and the feedback!
We're going to rebalance much of the combat after the jam. The weapons were meant to also get purchasable upgrades, to allow further customization, but we ran out of time. We'll work on the inertia/acceleration. We wanted the energy limit to be part of the strategy, but need to balance it better, especially late game. We made the first Energy Storage upgrade cheap to help early game, but it really depends on play style, and that still only gives a small boost until you get the regen. Once the core is balanced we plan to add late game procedural endless upgrades, along with new options for starting in higher difficulty dimensions.
Thanks again for recording your playthrough!
