Cool game! I liked the music, and the overall presentation. I thought the game did a good job of portraying a sort of off-kilter night time vibe. Even with relatively simple graphics and animation the game the atmosphere really comes across. I like leading goblins around and into fires to defeat them, and using them to destroy terrain, then disposing of them when you're done. It's a satisfying puzzle mechanic, and I think it could really have some cool depth with additional enemy types.
I couldn't figure out how to get past the brother (or even if there was a way to get past the brother) and a few times the camera got stuck looking at a room I wasn't in. That, plus the lack of checkpoints made it hard to continue, but I think you have the start of something really cool here!
