Honest impressions from someone who also builds idle games:
First-hour pacing: Tutorial is solid but the gap between understanding and feeling rewarded could be tighter. Idle games live or die on that first dopamine loop. A faster first skill-up with satisfying visual feedback hooks people before they tab away.
On prestige: It needs a clear why before players press reset. Show a concrete preview like After prestige your Woodcutting earns 2.3x so the reset feels like a reward not a loss.
Complexity: 10 skills plus gems plus familiarity plus mastery plus prestige is a lot. Consider gating behind milestones. Gems at skill 30, mastery at 50. Prevents early overwhelm and creates mid-game unlock moments.
What would keep me longer: Surprising cross-skill synergies. If Cooking 40 unlocked a Mining buff that is the kind of discovery idle players obsess over.
Core loop is solid. Keep going!
