Test it now.
I managed to launch the game. I had two folders, one with an .exe and the other with the rest of the files. I moved the .exe from the first folder to the second one and it worked! As for the game, I like the music and the style. I thinks it's a bit short and some indication of what to do would've been nice. (For example, making the prism flash when it gets shot so you understand it actually does something).
