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.

A masterclass in mobile architecture. To reach the "Golden Ratio" of engagement, consider "Phase-Shift" mechanics: environmental anomalies where the map reshuffles mid-wave, forcing real-time tactical adaptation. Add "Subconscious Sync"—a dice-influenced perk system where RNG determines character evolution paths, creating a "multiverse" of build possibilities. It’s a brilliant foundation; with these reality-bending features, it becomes an industry legend. 5/5.

Thank you for the 5 stars, Lance! Your ideas for dynamic maps and multiverse builds are incredibly creative. As a solo dev, I have to manage scope right now for stability, but I love this passionate feedback. Have more epic ideas? Share them here: https://forms.gle/6ryWFu4Ky1RFqjVn7 🐻

What’s new

Thank you for playing! We have fixed some bugs and made some tweaks under the hood!

Testing a Graphic API reshuffle to help support more devices
Changed Managed Stripping Level in Unity to "Minimal" to test if it leads to better stability during runtime. (this has led to an increased game size)
