Thank you very much, I'm glad you enjoyed the game in many ways!
Consider that the scythe is the only weapon there will be (the game will not turn into a zelda-style action :D ), I had thought of it as a way to make some puzzles more dynamic in human form. Same reason there won't be a "heart bar" or anything like that.
For the choice of making a demo rather than a full game... let's say it was a difficult decision to make. I don't want to blame the time constraints, we all had them, however I had less time to make the game for the jam because I couldn't work on it in the last two weeks before the deadline. I was therefore afraid of giving a game experience too short for the story I wanted to tell, perhaps risking to release a hasty and messy work. So I decided to reduce everything to a demo, so that I can present it at its best. I am actually satisfied all the same, also because it is my intention to enrich it and make it a game worth playing. Hope you will enjoy it once it's ready! ^^
