I was surprised how long I played (and survived) this one- I got to 592 seconds before deciding to just let the goblins take over the castle. It'd be nice to see the timer during gameplay, though I wouldn't be surprised if that was cut for time. The goblins are super cute, and I love the idea of turning a dropped object into an area-of-effect attack by shaking the ground. The ability to directly pick up and drop your enemies reminds me a lot of the old Flash game Defend Your Castle. Nice work!
