I like the idea, it's quite creative ! I had a bit of trouble to understand the system at first but after that it was kind of fun ! The little sound and animation when we hit the blobs is really satisfying ! ^^
Nice job !
EDIT : It would be a lot bette if you managed to make better controls, it's weird to click to move and attack at the time. If you split up those actions it would be a lot more satisfying to move ;)
