Good job!
One thing I really liked about this game was the unique art style and music. From this page, I can see that you made them yourself, which is especially impressive considering you only had 10 days to make this game! The art style is very creative, and it's clear you spent a lot of time on this - nice work!
One issue I had right off the bat was the screen resolution, which was really zoomed out for some reason. I couldn't read the whole menu, and when I refreshed the page, there was no way I could resize it. This made the gameplay quite difficult to understand, and I wish I could have played the game in the intended way.
I also noticed other bugs, as on the first level, I immediately just floated up into a void of nothingness, from which I couldn't escape. I was really interested in the game and would have loved to see more of the level! Because of this, it was hard for me to get a cohesive grip on the objective and mechanics of this game.
Despite this, I can see this has a lot of potential! You are clearly a skilled graphics designer and clearly know how to present a unique, out-of the box game. For the next step, I'd recommend sorting out these bugs and adding more polishing details, to allow this game to shine in its full glory!
