Really fun and loved the artwork! Managed to work my way through all of the levels.
I did run into one bug initially where I accidentally pressed “r”, thinking it would rotate the item, but it instead reset the level while I was holding the item. After it finished reloading, it thought I was permanently holding an item, so I had to hard refresh my browser to get back to a good state.
I liked the inclusion of a bouncing item and a floating item to vary things up. I think if you were to continue this game, I would like to see more specialized items like that where you would need to take not only their shape into account, but also the way they interact with other items.
