Loved the voices and the general feel of the game! Enemies were rather easy if you can circlestrafe or are in a long hallway, so I had a few dozen potions at some point lol because I didn't need to heal. At some point I just started ignoring enemies just to explore faster. I found the final boss but he just wouldn't die after circlestrafe hitting him for what feels like an eternity, so I continued exploring thinking I may have missed something, stacking more potions.
However, I ran into a gamebreaking bug. I tried to do the duality port in the big bad's arena, and it didn't let me. So I went outside his cage and did it again, but then it teleported me into a black void where I can still technically move (as in, the sounds play and the compass directions change when turning), but nothing happens... Oh and restarting the game via the menu caused a hard unity crash.
So I refreshed the page, gave it another go, slaughtered enough enemies to buff my damage into the 20 range, then finally killed the big bad :D in hindsight in my first playthough the boss had like 1hp left or something when I bailed lol
Nice game! Very disorienting and I had no clue where I was going since everything looked very samey. The duality rift mechanic was interesting but I didn't use it a lot. I'm one of those "I might need it later" people so I used it maybe 5 times in total across both playthroughs.
All in all I enjoyed it! Looks nice, feels nice, sounds nice, just needs a bit more variety and (for me) a bit more challenging combat. Good job!
