The idea is very unique, I loved how you have extended it further by having see-saws and the love smile following the crown to bring you back to life. Has good potential to become a full release if worked upon further. The physics can be improved a bit, sometimes the slime blobs got stuck in corners, the jumps seem very tight at places. Could have used a checkpoint in level 5 after growing in size.
Had fun, thanks for making it !
