Really enjoyed the atmosphere and ambition here. The pixel-art mechs and machine-beasts look fantastic, and "CHARGE is ammunition, cores are evolution" is one of the cleanest theme reads in the jam — charge doubling as both your damage resource AND your upgrade currency ties the whole loop together. I did a Swarm Matriarch hunt: manual clicks + the always-on auto cannon both dealing damage and generating charge feels good, and the skill tree is genuinely deep (5 gears, tiers, that huge node web) — buying Impact Coil and watching Combo Gear/Critical Math unlock next to it gave real "just one more node" pull. Nice touch that auto-fire keeps ticking while the tree is open.
One concrete bit of feedback from a desktop/mouse playthrough: the big "PURCHASE / UPGRADE" button (and the node tiles) didn't respond to my mouse clicks — even with enough charge and the button lit teal, clicking it did nothing. I could only actually buy nodes by selecting one and pressing Enter/A on the keyboard. A mouse-only or touch player might conclude upgrades are broken and bounce, so wiring pointer/tap clicks to that button would remove a real first-session snag. Everything else played great — well done!
