Hello IrreverentMrB thank you for playing our game! The new update pushed out has addressed the game difficulty with many changes to make the game much more fair and way way easier to get a longer run in without being too much of a cake walk. I don't think the bug for the hp changes for 9 to 10 were found but it could just be due to the circle radius not quite matching the real hitbox, but i'll look into it if it's still a bug! Thanks!
