Loved it! To hear your story that you have so much in store is most inspiring thing to say! The gameplay is fascinating, also unique take on multiple cam view, space action looks cool too. Donno how many surprises await but I noticed a bit of hiccup; where moving the camera/left-right is not instant. It's not any lag but the camera doesn't move in tandem with the character. And it's not the 'camera delay' & 'camera smoothness' fault. It's like, I swipe the screen and it takes time to center.

Thank you! The top-down view was added from feedback post-launch! I know you mentioned camera delay/smoothness is ok, but lowering both in the settings may fix the recenter time. It could be a nuanced issue so if you've tried this and it persists, please use this form: https://forms.gle/LWg7UCty9PyuxkjJ9 As a solo dev, every bit of feedback helps!

This is definitely something I'll be coming back to once the new episode releases. I was a little disappointed with how short it was, but I really should've looked harder at the title! A small critique I have would be the windows you get when parrying the Knight and Slaughterer are a little too short for how much health they have, but that's about it. Hope this gets bigger with us mobile enthusiasts.

Thank you for the 5-star review and awesome feedback! We're passionate about bringing premium experiences to mobile enthusiasts like you. You're right, this is the 'Genesis', a short, compact story to setup a larger saga! Great note on the Knight/Slayer parry windows for our next combat balance pass. Thanks again for the amazing support!

Phenomenal game! The graphics are truly stunning, and runs incredibly. The optimization is amazing. Major props to the devs! I barely have complaints. Story wise, it's very interesting. The games fun too. 😁 Though I do have a small nitpick. The lack of a jump button. I know that adding a new mechanic is not an easy task but I strongly feel that it would help the flow combat immensely. The game feels a tad too flat, maybe even restricting without it. -Best wishes, the Jump Button Advocate

The Advocate returns! Thanks for the phenomenal 5-star review! We're thrilled you love the 'stunning' graphics and 'incredible' performance, a ton of effort went into optimisation! And message received, Advocate! Looking into how a jump button could best fit into the game design for future updates. Thanks again for the fantastic support.
