Hot damn, this kicks ass! I love me a good boss rush and this is definitely hitting all the right spots with its excellent boss variety, simple yet expressive move set, and incredibly juicy and satisfying special effects that make even dying feel cool. As said, the gameplay is technically rather simple, but I thought it was really cool that there's a lot of neat tricks you can pull off as you experiment, such as utilizing the cyclone move right after an attack to stay in the inner circle layer for more damage or to dodge (this helps a lot with clearing the sword turrets next to Swordian of Earth while dodging his outer circle wave, for example).
If I were to have any complaints, they'd be small nitpicks like so:
*I wish I could hold down the button to keep slashing with the sword instead of having to click multiple times, but I guess you have a charge move so it can't be helped. Speaking of that, I wish I could hold to charge without being forced to have the initial click trigger an attack.
*I'm no stranger to very limited dash invulnerability, but I had so many times playing this where I swear I did a well-timed dodge only for me to eat an attack. Could just be me being bad, but something felt off.
*It's a silly complaint, but I do feel like once you get good, the bosses can get melted too easily, especially due to how generous the game is with limit break. Near the end of my session with the game it felt like I could just chain limit break after limit break and barely be vulnerable at all. I know that's because I've gotten better, but still, it just felt like a bit much.
In the end, my biggest complaint would be that I wish there was more to the game, and that's even counting the light/dark bonuses. You got me drooling for more, so I'm really looking forward to the sequel!
