Weirdly enough I reloaded the page and the bug stoped happening. I tried the game a few more times to try to get better, beat two enemies in a row and my combos improved a bit. I got bodied by the 3 vs 1 fight but thats to be expected.
If you are going to keep posting in the DDs, I recommend you to still support this html version and keep posting it. This is a fun game and it will be cool to watch your progress.
