Nice leveldesign! 

I like the particle effects and the puzzle layouts, my only complaint is that the greys make it kind of hard to see where one wall starts and another begins so I was a little disoriented. But I thought the platforming was engaging and I felt like a boss jumping to a platform and shooting it mid-air.

You have a great central mechanic, my friend! I'd love to see it fleshed out to its full potential.
