Though I have seen this theme concept a few time already, how you have implemented stands out among those I have tried, and I really like the gameplay you have done! The switch-parry mechanic is extremely fun, although I can't quite guess if I should parry when at the red or green part of the bar as I can't notice any differences. The known bugs, especially targeting the same goblin over and over, did kind of take away from the switch-parry mechanic quite a bit, but I can definitely see myself playing this on my own, like e.g. on my phone to kill time. Well done!
