Since I'm going to be doing a lot of commented reviews, I'll keep it well structured by supplying you a reason with each of my ratings.
Game Design - 3 Stars - Honestly I feel like you have the potential to do way better with your level design. Most of your levels were incredibly easy and some of them, I didn't even need clones to complete! Honestly the hardest level was getting to the start button lmao. There's also a glitch where you can stick to the side of floating platforms so I used that to get my way through some of the levels without using any clones. I think your level design needs polish.
Fun - 3 Stars - I had a fair bit of fun as I was faced with a bit of a challenge at the beginning since I really had no idea what to do or what I should be doing. I almost quit but I was determined to figure out how to use the clones to climb and move around and I eventually got the hang of it. I think your cloning mechanics could use some work and polish since it's really wonky.
Innovation - 5 Stars - I honestly think this is the most unique take on the theme I've seen so far and I'm impressed with your idea, but I just think your game design needs some work.
Theme - 4 Stars - It fit the theme pretty well since it took a "chaotic" amount of clones to reach the destination for some levels. I think it could've been handled a tiny bit better (Hence 4 stars instead of 5) but it was pretty good! Nice job!
Graphics - 3 Stars - Nothing really to say about the graphics. I liked the effect you put on the clones but that's about it. It's pretty simple, not really bad or good.
Audio - 1 Star - Bro that music was so irritating to my ears. I really have nothing positive to say about it, I'm sorry.
Overall, I'd say this has the potential to be a very good game if you put more work into it. You said you only made it in 5 hours at the end screen but you had a whole week to make it! I think you should've put just a little more effort into polishing and making sure everything worked properly at the very least. You did a decent job but this has really high potential to be wayyy better than it currently is.
