My first question was: why is the main character half naked while in a winter environment? Then I recognized the Malbers Controller where this is the default character. Hm. Would have been good to exchange the model though, but we all know time is short in a GameJam.
The windows build did not go to fullscreen. So, reading the intro text (which vanished too early) was not optimal on my laptop screen. I had no cursor to change the window size, and when I pressed ESC to get it back, the game exited. Hmm.
70 seconds to find 7 fire places in this big viking village is not much. I found 4, including the phoenix fire place and the cave. Not everytime I was there the fireflies where recognized at all, and finding to get to a better suited place to "catch" them did cost time I did not have anymore.
Aside from that, everything looked good, the controller was fun, the music was nice, and I liked the lantern light effect. However, I am not a big fan of "reset and try it again" games. On Youtube there are some GameDevs who recommend "Anything gets better with a timer on it" but I doubt that. Especially a story with a spiritual background should be able to take its time to convey the story which was thin here. I would have preferred some inhabitants who could say something regarding to the task, the spirit tree and directions to the fire places, without the pressure of a timer. But hey, it's your game.
