Brutal but every single point was real and they're all fixed in the current build. Receipts:
"Bosses are immune to clicks with no explanation." They weren't immune — your taps were just landing invisibly against a huge HP pool with a hitbox sized for goblins. Boss tap radius now scales with sizeMul (a 2.55× ram had the same 9-pixel hitbox as a normal goblin), and every tap spawns a floating damage number so you can SEE it landing.
"Archer aiming and arrow speed makes no sense." This was the worst bug in the game. Heroes were firing at where enemies were, not where they'd be — arrows landed behind moving chargers basically every shot. Fixed with full intercept-quadratic target leading on every projectile-firing class. On top of that, projectile lifespan now scales with range / projSpeed so long-range bolts don't vanish mid-flight, and there's a new hero leveling system with crit chance scaling 0% → 30% per level.
"Enemies spawn off screen / Archer enemies stay entirely off screen damaging you." Ranged enemies' stop position is now capped at W - 18 so any archer goblin that's actively shooting the wall is guaranteed to be on-screen and tappable.
"The skill menu covers part of the screen." Shrunk #skill-panel (narrower min/max width, tighter padding, smaller font) plus a mobile-landscape override that goes smaller still. The battlefield stays visible.
"Browser zoom moves enemies around." This was a real bug — resize() re-derived canvas W/H from innerWidth on every zoom tick, which visibly shifted the simulation. The handler now short-circuits when visualViewport.scale !== 1, so Ctrl-+/− is a no-op for game state.
"Super grindy / spent an hour, can't afford the first skill." RP yield is up +25% per wave, you now start with 3 hero slots open (was 1) so you can field a real team from run 1, the first skill is way cheaper (5 RP + 15g for Smite, was 12 RP + 25g), and the skill bar is visible from your very first wave so it doesn't take 2-3 runs to even discover skills exist. Plus a 1× / 2× / 3× game speed toggle in the top-left.
"100 upgrades but the archers keep missing what's the point." This was the heart of it. Lead-targeting fix means archers actually hit moving things now. Affordable research nodes pulse gold so you know what you can buy at a glance. And there's a new Bestiary in the Pause menu that explains every enemy + boss including the Goblin King, Bull Champion, Iron Vanguard, Master Archer, High Priest, Coven Matron, and Siege Lord boss variants.
Polish was the part you said was already fine. The balance and bugs you called out are the ones we burned through this update. If you've got the time to take another run at it, the rough edges you hit are gone. Either way — your write-up was concrete enough to actually act on, so thank you.
