Hi! Thanks for playing the demo and for your comment, this is exactly the type of feedback I was hoping for!
A tutorial is in the works, I was interested to see how far players got without one! You're also not alone thinking the hitboxes are a bit too small! I plan too improve this too.
The browser freeze after loading is unfortunately expected due to web limitations. WebGL is only single-threaded and there's a bulk operation that runs after loading to prevent gameplay stutter.
I'll keep working on optimising it. Did the performance improve once the game started?
Be sure to revisit Swinghammer in the future to see your feedback taken on-board!
