Neat game, I do have some criticism about certain aspects:
1 - The theme: I think you interpreted the theme of "LOOP" in the fact that you need to loop to effectively kill the enemies which works, sometimes... I do feel like it's a somewhat weak approach to the theme, wishing here there was more tied to "LOOP"
2 - The Itch Page: I can't read and write, I think the BG and FG colors are way too similar
Otherwise good music and graphics, nice stuff!
Good luck!
