Very interesting concept idea. This could very easily become one of those puzzle games with a simple mechanic, but surprisingly hard puzzles. Right now, it seems very slow and precise. Instead, I would recommend to try and focus on some fast game play and puzzles. Some tips on how to accomplish that would be to add some quick movements for the player like sliding and wall running and especially add an aim assist. A game that uses aim assist would be like the green shells in a mariokart game. I would recommend you look into that. Great starting game and concept for a week!
