Fun game with amazing visuals! Seriously I love how it looks with the lighting and particles, such a cool atmosphere! And the health bar looks so cool with the animations. I don't usually play action games much, but I enjoyed the combat here, and appreciate that defeating enemies heals you. I feel like the difficulty really spiked with the second boss though (needless to say I did not beat it), I also got used to being able to block attacks completely and didn't realize I was taking damage until my character died onscreen. I think it would be nice if the respawn point was closer to the boss battle, but maybe that's just because I keep failing there. (Also, I noticed that the first tutorial text says W, D to move, when I think it should be A, D?)
Overall, really well done, I'm super impressed!
