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!

to sum up the game it's very inconsistent especially the hitboxes on melee weapons animations don't feel that fluid camera controls are too limited same with customization there isn't any feeling of difficulty even though it seems hard game feels like it was a passion project from a single idea that isn't fleshed out

Thank you for the honest review and for giving the game a chance! As a solo dev, feedback like this is incredible. I am always iterating on the combat flow, and tweaking the camera and player options in updates, so I will definitely look at your notes. I would love to hear more of your insights here: https://forms.gle/LWg7UCty9PyuxkjJ9

I beat it twice, it was fun action. my gripe is that the character model's head is 2x larger than his body, looks like a kid, draws away from suspensful epic immersion? GG.

Thank you so much for the 4-star review! As a solo-dev, reading that you beat the game twice is a huge compliment. I hear you on the helmet size breaking the immersion. It is a stylised choice, but I will definitely look into offering some more grounded, realistically-proportioned variations in future updates. Thanks for playing!
