This is a nice take on game dev theme, it really feels like I'm building my game while getting distracted by errors and warnings. Not sure if player is needed here though. There's a lot of sliding, so I guess collisions could be a handled better. I found only one bug so far: you can drag blocks into a platform. But it doesn't ruin the expirience :)
