You marked the game as having Linux and macOS builds, but as far as I can tell there is only a Windows version inside the archive. Please adjust the tags accordingly. I was able to run it through wine on Linux, but I had some problems as there was no text visible and I couldn't quit the game without killing the process.
So the basic mechanic seems to be alright, I can jump and dash and collect things, but I actually have no idea what I'm doing there. At some point a red curtain fills the screen and I can't do anything anymore, so I guess I'm missing something here.
In my opinion the game does not really benefit from being 3D instead of 2D. In 2D (side perspective) you could much better assess if or when to jump, if you can make the jump etc. Though the graphics do look nice.
