Hey Alex, thanks so much for playing, we've heard that the melee combat feels delayed before, the game is a bit laggier on slower machines, but runs much smoother in the downloaded version. We also decided to make the attack feel abit stiffer to dissuade the player from trying to use a super offensive "run and gun" type style(it shouldn't be too stiff though I think that maybe due to the laggy webgl version)
The exclamation mark query confuses me abit because it is blue and most are the enemies are grey/black? I think I see where you are coming from though. We decided to make enemy attacks quite fast because the game is meant to be quite focused on the invisibility mechanic and dodging around/hiding as opposed to fighting everything head on, choosing to fight head on is meant to be quite difficult. I think the comment on the music is also quite fair, we had limited time constraints and will look to improve on it after the jam ends.
Thanks for such good feedback!
