I am impressed that you have been able to develop these assets during this JAM time. The game starts well, but I found it confusing. It is not clear what should be done, why or how. The controls are classic in first person games, but they are VERY responsive. They almost mess up rather than help, you could rethink them a little. Congratulations on the game, it was not very clear where the "30 second quest" is inserted, but surely we have something that can be evolved and become a great game.
You need to reach the top of the tower within a target time shown in the bottom right. When you do, you'll get a new ability allowing you to reach the tower even faster. Ultimately you'll be able to reach it in 30 seconds, which is how you free your soul (and win).
Give it a try :)
