Cheers thanks for playing and the notes!
The reaction times of enemies do get steadily shorter, and it's cool you didn't have trouble until the final boss! Most of my pals that played started finding it more difficult before that.
And yeah, originally you lost if you struck too soon to prevent cheating and a fake out mechanic, but it was too buggy to implement before meeting the jam deadline. Post jam though when I can add features in it could come back =)
Thanks again!
