Thanks for the detailed write-up — you flagged four real problems and they all got addressed in subsequent updates.
Save loss on restart. Added visibilitychange / pagehide / beforeunload flush handlers so progress writes to localStorage on tab close, page hide, or browser shutdown — not just at run end. Also added a one-time Save Backup nudge that fires after 3 runs pointing you at Settings → Export Save, which copies your full save to a paste-anywhere code. That's the real safety net — browser storage can still get evicted under disk pressure or by clearing site data, and only an export survives that.
Grind. RP yield up +25% per wave, you now start with 3 hero slots open (was 1) so you build a real team from run 1, first skill is way cheaper (5 RP + 15g to equip Smite, was 12 RP + 25g), and the skill bar is visible from your very first wave so you know skills exist. Plus a 1× / 2× / 3× game speed toggle in the top-left to chew through the slower stretches.
Units useless even with upgrades. Root cause: heroes were firing at where enemies were, not where they'd be. Arrows landed behind moving chargers basically every time. Fixed with full intercept-quadratic target leading on every projectile-firing class (archer, mage, crossbow, cleric). On top of that:
- Cannons now always splash — shells detonate on a timer at the predicted impact point, so even if the target dodges the splash still lands.
- Projectile lifespan now scales with range so upgraded mage / cleric / crossbow bolts don't vanish mid-flight.
- Mage / Crossbow / Cannoneer / Cleric base damage all nudged up.
- New: Hero leveling + crits — every hero earns XP from kills, levels up, and gains crit chance scaling 0% → 30%. Crits hit 2× and inherit through splash/chains.
Auto-clicking. This is now a first-class feature, no external tools needed:
- Hold-to-damage — press and hold your finger / mouse on an enemy to chain-tap them.
- New Restless Hand research node (Command chapter, 4 stacks) scales the hold-tap rate up to ~5.5 hits per second.
- Sentry Marksmen research auto-taps the closest enemy automatically while you focus on upgrades.
Bestiary, hero panel DPS / KILLS / LVL / Crit% display, range indicators, and a real commander rebuild also shipped. If the artwork pulled you in originally it might be worth another shot — appreciate either way.
