The music fits perfectly for this game and builds the atmosphere. The dialogue box style matches the visuals without being out of place, but it is frustrating to see the dialogue appear every time you die even if it is only so often in a game. I assume it is because the level is restarting over and over when you die. Either save the fact that the dialogue has been read (can be a lot of work) or have a level / section just for dialogue with minor risk of dying (which is done all the time in games). I love the orb throwing and losing heat from it which makes the choice to throw a risk, I like that.
The warmth bar drains too fast after throwing it which is ok if it was towards the end of the game but not early on however if you are trying to make a game that is intentionally hard then forget what I have said. Any game that developed by yourself will be easier than for the player as you have in-depth knowledge on how to progress while they are playing blind. The level overall is a well-designed platformer, and it was fun to play. If you get the chance, play my game, Thanks.
