The game has a great atmosphere — you really nailed that dark, moody vibe! It definitely pulls you in. One thing I noticed: the character moves from right to left through the levels, which felt a bit unusual at first, since most games tend to go the other way around. Not a big deal, just took a moment to adjust.
Also, when the character activates a lever, it would be nice to see a quick shot or visual cue of what exactly is being powered or opened. That small addition could make the gameplay feel even more intuitive and satisfying.
