I like the flashlight mechanic. I don't think it was communicated very well tho. There were the signs that showed you how to do it but I couldn't tell what it was for. Fun mechanic tho!
The art was pretty good and I think it fit the theme pretty well.
I don't think the platforming aspect was particularly good. In fact, it was a bit frustrating. Especially on the boss with so many tight jumps and the framerate drops a lot. Many small hidden collisions would cause me to die. I couldn't beat the boss. And I tried for a good amount of time haha.
I love the aesthetic and I think it's a clever game! Great job!
