This is going to sound really weird, but when I was younger, I had a dream about my perfect game. It was basically an open-world version of Mirror's Edge without gunplay. It was more of a whimsical experience like Jumping Flash, taking you on a dream-like journey through a world, with an emphasis on free-falling.
Kersploosh! is basically a bite-sized realization of that game -- albeit a very brief, fleeting, yet enjoyable experience. It's a bit one-sided at times, but ultimately, it gives you exactly what it advertises: the ability to drop objects into a well and have fun falling down it.
