It's a great idea, and I like the art style a lot, but the pixel art is a bit jittery, at least on my end which makes my eyes tired very fast and it makes it a bit difficult to see what the obstacles are.
It's also fairly brutal that you have to start from the very beginning whenever you lose ^^' There was also one time I glitched through the floor and ended up going bankrupt - but I do believe there's a great idea there that would be a lot of fun if you had a bit more time to work on it
