Thank you for such detailed feedback! The new build fixes the stutters and freezes: the game leaked graphics resources over time (the browser version suffered most), and the skill tree screen no longer restyles every node on each click. Other fixes in this build:
- Starter towers from Garrison now let you pick their kind (archers, cannon or frost) for free.
- The Moneylender's tooltip now shows exactly how much gold to hold for the full interest this wave.
- Castle health and wall health are the same thing. The health bar's tooltip and the skill texts now say so.
- The ability buttons show their real damage/healing and cooldown, and you can use them with Q and E.
You're right about the grind around wave 50 and about Arrow Rain and Repair being weak. We're working on both next.
