Hey, nice submission! Great job on making it through your fitst game jam and ending up with something pretty cool!
One issue I had is that I didn't really know what I had to do or where I had to go for quite a bit.It's only after a while that I managed to notice the objective. What you would want is to design your level in such a way that player can almost always see their objective, or at least see it at their starting position. Another thing I'd look into is the level's lighting - some parts of the level were quite dark (at least on my screen), so I had a hard time finding my way around.
That being said, I still think you did great, especially for your first game jam! Good luck with further development of this game and great work!
