Thanks a lot for playing, i'm happy you liked it!!
For the bug side yeah sadly i didn't had the time to fix all the bugs, we were still working on more content when we deployed this smaller demo of what it should have been, but some you listed are not bugs the more damage if you are more near to the enemy is intentional, is to remember the player to have some distance during a sword fight!
But for the others you have listed i will fix them in the next updates
