Cute game. I was impressed how much it explores the possibilities of throwing the rock around, I liked the part where you had to dash to pick it up in midair over a spike pit also the part where you had to arc it over the large dirt square to hit the lamp. Overall there are a lot of good obstacles that complement the main character's abilities.
(as an aside)
So who did everyone get for their waifu?
"I got Rei!"
"I got Asuna!"
