The art is amazing and the world building is interesting.
However, the bosses felt too unforgiving. Parrying the laser attacks takes time to get used to, they can kill you extremely fast if you aren't fast enough. I feel like they could be a bit more forgiving, either like being more telegraphed, dealing less damage, or allowing you to start parrying halfway through the attack. Right now, if you miss that timing, you are pretty much dead or almost dead from a single laser attack. Still, balacing is something that can be fixed, while the art ir beautiful and idea of the game is really cool, I'd really like to see it developed further, good job!
