The pixel art is beautiful! The snow, the atmosphere of the cave, the sound of the pickaxe, the movement and creak of the rope were pleasant.
It took me about an hour to clear the first version. I think the combination of a non-expansive map and a time limit is a good idea because it's tense.
About the version with no time limit. If the maps were more expansive and there were more save points, it might be a more voluminous game like Metroidvania.
But the current length is also just right and I like it.
Thanks for the nice game! From a user in Japan.
