Thanks for your feedback. Action time based is a very old battle mechanic as it was patented by Square Enix (really) for Final Fantasy 4 until Final Fantasy 9. Thankfully, it's no longer patented in 2014. At first, I was thinking of making the game to be just turn based system, like the usual. However, I thought that action time based would be fun to try on since there's very little games I've played use that mechanic. And yes, more sound effects would be good. However, I didn't have time to work on it. I had only less than 24 hours to add the sound effects and music to the game.
Also, ignore the bug. I have zero intention to fix it as I'm too tired to find how it happened.
