I just wrote a very detailed bug report and review, but Apple deleted it so Ill just jump right to it.
In the level "The Armory: No Blade Sharper", if you pull any of the levers before fighting the second Pygon, when you do engage the Pygon the camera will be facing away from the battle. You wont be able to move or turn the camera, but the Pygon will start hitting you. After a second or two, Horn will glitch through the floor and fall below the map, and youll get the usual "You were defeated" message. This bug does not occur if you fight the Pygon BEFORE activating the levers.
I also noticed a minor graphical glitch in this same level. In the second-to-last tunnel, in the back corner to the players right, theres a sun-glint, despite there being no sky access in the tunnel. This isnt a big deal, but if the developers want a perfectly polished game theyll want to fix this.
The dodge controls are also very unresponsive. They work maybe 50% of the time, but probably even less than that. Please tweak the dodge controls responsiveness.
I havent finished the game, but I thought Id report these bugs. I hope the developers still read the reviews because the falling-through-the-floor glitch has got to go. Thanks for reading.
