Hi shadowhunter2468!
This is a very neat concept, particle effects are awe inspiring and the polish and the post processing is on point. It could really use some sound effects on those explosions! It was pretty tough as well. I would recommend starting more simply in your level design, so the player has time to learn the mechanic and get used to it. Then you can drop them in lava.
Overall a fun idea and a great start!
Best,
