Got to the end! I absolutely adore the look and feel of the game, awesome art and music that really feels like it was ripped straight out of hollow knight! The mechanic of taking pictures of things to stop them is great too. I like that there were hidden switches too that you could only get to with the camera.
If you're looking to make any improvements, the platform feels a bit wonky, like I would be standing on a platform and fall through it if I wasn't directly on the center. There was also an area that had a switch you had to hit, but there was a light above it that said it needed a switch. When you put your mouse over the light, it shows the platform but won't let you take a picture of it. If you try to hold the camera over that light, you fall through the platforms. I figured out later that taken a picture of the light wasn't a switch (yep I'm a dumb dumb, but I got a bit confused)
Anyway, hope you do great!
