I tried for 15 minutes and barely managed to get past 50% of the first boss. I could hardly even see the game's roulette. I had a lot of trouble dodging the first boss's dash attack because it's so fast and leaves little time to react, especially at close range. On top of that, I took a lot of damage trying to hit the boss, the attack range is really short, so I kept bumping into the boss, and again, I had to get close, which meant getting hit by the dash attack. That said, I really liked the art, it looks great, and the sound design and music are awesome too!
