Damn this is one dangerous house :D
The music and atmosphere kinda reminded me of the games by Freebird Games (To The Moon etc) so I was instantly hooked haha, also really liked the art style and fullscreen ending images ! The concept of the lantern dying out after 20 seconds is a good idea. And you did a great job with level design to make sure there's just enough time to reach every ending but to still make it challenging.
It's obvious that a lot of effort went into making this little game, especially with how the light of the lantern interacts with walls and creates shadows, that was a very nice touch ! You all can be proud of what you've done, the end result is beautiful and has potential :)

I've noticed slight bugs or things to tweak in order to make the experience even better if you expand the game after this jam. Should I also add this more detailed feedback here or would rather have me send a message somewhere else ? Not sure what's best so I figured I'd ask before sending a long message haha.
