Hi! Thank you for playing and for providing feedback! Yknow, when I playtested the game myself, the default attack seemed to work just fine. But two people who tested it for me as well also complained about the difficulty with it. So I'm not sure why that ended up being the case, but it's something I'll work on!
About the health on the screen, one of the controls mentioned is pressing E to show/hide the HUD. That should make visible the HUD that shows the player's health on the top left and enemy health on the top right. My mistake though, I should have made it visible by default.
