*(Revisiting for some more in-depth feedback)
First off, it's such a simple looking game but sometimes that's all you really need. This game felt so Brackey's inspired to me in the gameplay & visuals, which was nice. I loved the ability to wall climb & the little particle effects added to the lava made it feel less like a rectangle & more like something that could melt me if I touched it. It did take me a few runs to get through but the music made it feel scarier each time I tried to get through.
I also appreciated the inclusion of a Youtube preview of the game & how it didn't spoil the end. I could see what I was getting without compromising anything.
What I liked the most: The post-processing!! I love the effects you've used for this. It really helped to elevate the simplistic art you used & made it more exciting visually. Also even though you didn't make the music, your choice of what music to used matched the game very well.
What could be improved on: I would have liked some checkpoints for this, even though it was short, I feel it would have made it a little less frustrating to get through to the end. Also a big issue I had when playing was that the camera didn't pan down when you go to move platforms, so I'd die a lot which was quite frustrating. Having some sign before you go down, or a camera pan added would be a nice addition.
TLDR; A simple game made well. A subtle horror which leaves you on edge the whole time.
