Procedurally generated levels have the disadvantage of being able to provide worse-than-adequate levels. Since games should supply the players with an appropriate difficulty curve and well-designed-placed thrills, procedurally generated content is not preferred when it is not just a tool to provide a chaotic environment such as in survival/sandbox games.
Of course, providing the player with hundreds of hand-crafted levels is not so possible for a game jam game. But, I'd prefer playing 5 unique hand-crafted experiences rather than trying to find my way in more procedurally generated mazes that probably won't provide any thrills. For example, that enemy you have implemented in the game can be utilized in certain levels in the game to create thrilling moments, but since the levels are procedurally generated, that is most of the time is not the case.
As I remember, the game crashed after I entered a new level and pressed the space button several times. I couldn't reproduce that though, sorry!
