Nice idea. Some more feedback when you get hit would be useful, and maybe more of a tutorial before it gets difficult. Really love the visuals.
Thanks much for trying it out. There's a rather distinctive sound and screenshake when you get hit, but i agree that some particles and a losing heart animation would help. That's right, the difficulty curve is unusually steep in this game, but i couldn't smoothen it up enough in just few hours. Thanks for the effort of playing the thing and stating your opinion!
