Hey, I've been recording your game and I wanted to give you some feedback that hopefully ends up being useful to you :D
-The visuals are quite simple but they fit the game very well.
-Voice acting was pretty good and the history was very interesting and kept my interest growing through the playthrough.
-At the video you can see that I've found some very strange bugs/glitches that could have broke the game but luckly they didn't but it would be good to keep an eye on them.
-I would make the "cooling rate" more harder and give more "warming power" to the items so the are required to used at least once because I didn't get further than 1/3 or 1/4 of the "cold bar" during the gameplay.
-Even for this being a game for a Jam I consider that developing the game further could end up in having an awesome game that you could put at some online shops and people will surely have interest on buying it.Because dude as I said before, the history is very very interesting.
The game is quite great and I hope you keep working on it. Hopefully this is useful for the development :D, also if you could subscribe that would help me a lot :)
Regards
