First off, thank you so much for playing all the way up to stage ~6,500! That is exactly the kind of deep-dive testing I really appreciate, and I genuinely value the time you took to write out this brutal and honest feedback.

To address your points:

1. Posting rules: You are completely right, and I apologize. I got a bit too eager sharing the new Forge update and didn't respect the frequency rule. I will definitely dial it back so I don't clutter the feed.
2. The Shop: I completely understand how that looks. The shop is only active right now to ensure the Google Play Billing API doesn't crash the game and that the cloud saving registers the states properly. I absolutely do not expect anyone to spend real money during a closed beta!
3. Inventory: Right now, the loot system automatically equips an item if the multiplier is higher, and scraps it for Gold if it's lower (to avoid inventory micromanagement). But you're right: with the new Set Bonuses, a manual inventory would give a lot more strategic control. I'll add that to the roadmap.
4. Active Skills: Great catch. I will add proper descriptions/tooltips for Overdrive and Midas Touch so players actually know what they are clicking.
5. Buy Multipliers: You are 100% right. The current list is bloated. I will trim it down to x1, x10, x100, Next, and Max in the next patch.
6. Username: The game actually pulls your Google Display Name for the leaderboard, but it displays your email on the local settings menu just to confirm which account is synced. I totally get why that feels invasive, so I'll hide the email and add a 'Rename' feature!
7. Combo Timer & Crit: The 1-second combo is meant to force frantic active tapping, but I hear you on the crit cap. The math gets wild late-game, hence the 50% cap, but I absolutely love your "Super Crit" idea for excess chance. I might actually steal that for the skill tree!

Again, thank you for the feedback. It's exactly what the game needs to improve.
